fracturing in olivine indicate moderate shock. Thin veins of secondary
carbonates are present, most likely due to terrestrial weathering.
Major element composition (P. Bland, OU) estimated from the
mean of 256 broad-beam microprobe analyses (spot size 20 m,)
indicates a komatiitic IUGS composition (SiO2 = 47.22 wt. %, Na2O

Martian meteorite (basaltic shergottite)
A single stone of 15 g, covered with fresh black fusion crust, was
recovered by an anonymous finder within the province of the other
Dhofar meteorites. Classification and description: (Y. Ikeda and M.
Kimura, Ibaraki; H. Takeda, Chiba): it has a doleritic or
microgabbroic texture and the grain sizes of the main minerals
(pyroxenes and plagioclase glass) are ~1 mm across. It consists mainly
of ferroan pyroxenes (augite and pigeonite), and plagioclase glass
with quenched plagioclase rims. Minor minerals are hedenbergite,
pyroxferroite, fayalite, silica, Ti-rich magnetite, ilmenite, sulfide,
phosphate, and rhyolitic glass. The Fe/(Mg + Fe) ratios of pyroxenes
(augite and pigeonite) range from 0.40 to more than 0.90, those of
hedenbergite from 0.97 to 0.99, and olivine from 0.90 to 0.98. The
original plagioclase grains were transformed to plagioclase glass
(An35 to An55) by an intense impact shock, then quenched plagioclase
of the same composition a few tens of micrometers up to 100 m in
width at the boundaries between the plagioclase glass and other
minerals. Oxygen isotopic composition (T. K. Mayeda and R. N.
Clayton, UChi): ä18O = +4.46., ä17O = +2.52.. This meteorite
was recovered from an area near the Dhofar 019 basaltic shergottite,
but the two meteorites are probably not paired. Dhofar 019 is doleritic
and contains olivine grains with Fe/(Mg + Fe) ratios of 0.4.0.75,
while these seem to be absent from Dhofar 378. Pyroxenes in Dhofar
019 are more magnesian than in Dhofar 378. Specimens: type

Lunar meteorite (feldspathic crystalline matrix breccia)
One 34.4 stone was found in the Dhofar region of Oman.
Mineralogy and classification (H. Takeda, Chiba; T. Ishii and M.
Ohtsuki, UTok): A feldspathic fragmental breccia consisting of clasts
of various lithologies embedded into a fine-grained crystalline matrix
(crystals up to 0.04 mm in length). Clasts include cataclastic feldspars
up to 1.8 × 0.6 mm in size, plus dark fine-grained impact melt breccia
3.3 × 2.3 mm in size with feldspar fragments. Plagioclase
compositions of An95.97 are within the range of lunar anorthites.
Pyroxene crystals in plagioclase and crystalline matrix range from
En75Fs21Wo4 to En85Fs10Wo5 with FeO/MnO (wt%) = 57. Olivine:
Fa15 to Fa24 with FeO/MnO (wt%) = 78. Fine Ca carbonate veins
penetrate into the specimen. Unlike known lunar meteorites, this
lunar rock is a feldspathic crystalline matrix breccia. The most Mg-
rich pyroxene is more Mg-rich than those of common lunar regolith
breccias and similar to those of 60019, an Apollo 16 breccia containing
poikilitic clasts. This lunar meteorite differs from other known lunar
meteorites from the Dhofar region, which are either feldspathic
regolith breccias or fragmental breccias. Specimens: type specimen,

Lunar meteorite (anorthositic fragmental breccia)
A dark grey, crusted stone weighing 34.05 g was found in the Dhofar
region of Oman. Classification and mineralogy (A. Greshake,
MNB; M. Kurz, Kurz): meteorite is an anorthositic fragmental breccia
consisting of clasts of various lithologies embedded into a
glassy, partly devitrified fine-grained matrix; the clast size is generally
below 3 mm; vesicles are abundant; feldspar: An96.0-99.3; pyroxene:
Fs11.5-35.7Wo8.2-44.9 and olivine: Fa30.6-50.0; augites dominate over
Ca-poor pyroxenes and often contain pigeonite exsolution lamellae;
accessory phases are Fe-Ni metal and ilmenite; crystalline fragments
include microporphyritic impact melt breccias, intersertal impact
melt clasts, gabbroic anorthosites, and large feldspar; no mare basalt
clasts and no glass spherules have been identified; feldspar generally
shows pronounced undulatory extinction and sometimes mosaicism
indicating strong shock metamorphism; the meteorite is moderately
weathered; gypsum, celestite and calcite occur in cracks and holes;
Dho 490 may be paired with Dho 280, since they were found nearby

Achondrite (ungrouped)
A stone weighing 116 g was found in the Dhofar region of Oman.
Mineralogy and classification (C. Lorenz and M. Ivanova, Vernad.):
the rock is a metabreccia and consists of at least three different
lithologies: pyroxene-feldspar, pyroxene-olivine and pyroxeneolivine-
feldspar. In texture the lithologies vary from medium to
coarse-grained, poikiloblastic to equigranular. Mineral chemistry:
olivine Fa4.8; CaO – 0.13 wt.%, Cr2O3 – 0.42 wt.%; orthopyroxene
is En95Wo2, Fe/Mn ratio is 6 (at); feldspar is An13-34. Olivine and
pyroxene are of the same compositions in the lithologies. The minor
phases are Ca-rich augite En52Wo44; Cr-rich troilite (up to 3.11 wt.
% Cr), chromite and essentially rare minute grains of Fe-Ni metal.
Weathering grade is W3. The oxygen isotope composition (R. N.
Clayton, UChi): d18O = +9.21‰; d17O = +4.29‰; .17O = –0.49‰,
is not in the range of known meteorite groups but close to the winonaite-
IAB-IIICD trend, and ureilites. Mineralogically the meteorite
may have some links to primitive achondrites but compositions
of olivine and troilite are close to those in polymict ureilites. However,
this meteorite lacks a carbon-rich matrix. Specimens: a type
specimen of 23.5 g and a thin section, Vernad; main mass with

Chondrite (ungrouped)
Many stones weighing a total of 204 g were found in the Dhofar
region of Oman. Mineralogy and classification (M. Ivanova, Vernad;
L. Taylor, UTenn): the meteorite consists of chondrules, 0.08-
3.2 mm in diameter, (0.86 mm in average) of different types, PO,
POP, BO, RP, CC, and their fragments embedded in a fine-grained
matrix. Chondrule/matrix ratio is 1.1. Olivine and low-Ca pyroxene
have large compositional ranges: olivine has Fa1-50, CaO – 0.2 wt.
%; Al2O3 – 0.06 wt.%, Cr2O3 – 0.09 wt.%, PMD of Fa – 42%; low-
Ca pyroxene is Wo2-3.5En53-95; chondrules contain glassy mesostasis.
Accessory minerals include: pigeonite, chromite, troilite, rare hydroxides
and essentially rare FeNi metal (Ni 5 wt. %; Co 0.4 wt. %).
Thermoluminescence studies (A. I. Ivliev, Vernad) indicate petrologic
type 3.2/3.3. The meteorite is heavily weathered, and some
silicates are altered. Weathering grade is W5; shock stage is S1.
Based on the very low abundance of FeNi metal and hydroxides,
Dho 535 could belong to either the LL or R chondrite groups but
with very abundant matrix. The average size of chondrules is consistent
with LL chondrites. A histogram showing the distribution of
olivine is similar to unequilibrated ordinary chondrites. FeNi metal
is mostly kamacite, typical for H chondrites and unusual for R
chondrites. Sulfide assemblages and chromite chemistry are also
unusual for R chondrites. The absence of refractory objects and
olivine chemistry distinguish Dho 535 from C3 chondrites. Oxygen
isotope composition (R. N. Clayton, UChi): d18O = +8.56‰; d17O =
+4.96‰, .17. = 4.51‰ is unusual for any chondrite type. Specimens:
type specimen of 46.8 g and thin section, Vernad; main mass

Ordinary chondrite (H4, anomalous)
The sample (working and find number: OM 1.01-24) was found as a
single fragment of 60 g in the Dhofar region. Mineralogy and classification
(A. Bischoff and A. Sokol, Mün): Although the chemical
analyses of olivine (Fa18.5) and pyroxene (Fs16.8±1.2) are similar to
those of H-chondrites, this rock is not a typical H-chondrite, and
consists of much more matrix than typical ordinary chondrites. R.N.
Clayton (UChi) states that Dhofar 622 "has a lower .17O than any
ordinary chondrite we have measured (typical H-chondrites have
.17O = +0.7)". The oxygen isotope data are: d18O = +5.15; d17O =
+2.92; .17O = +0.25‰. The meteorite is very weakly shocked (S2)
and moderately to heavily weathered (W3-4). Specimens: main mass

Dronino ....................................54'44.8΄ N, 41'25.3΄ E
Ryazan district, Russia
Found July 2000
Iron, ataxite (ungrouped)
A 40kg iron was found by Oleg Gus’kov, Moscow resident, as he
was returning home from collecting mushrooms near the village
of Dronino in the Ryazan district. In early 2003, it was taken to
Vernad, and identified as meteoritic. In summer 2003, scientific
expeditions and meteorite hunters collected more than 600
fragments (the largest is 250 kg) totaling about 3 000 kg and
occurring at a depth of 0.2-2 m across an area of 0.5x1.5 km. The
distribution of the fragments suggests that the meteorite formed a
now-buried crater about 30 m in diameter. This crater is not
reflected in the present-day topography of the site. No historical
records exist of a meteorite fall, thus it appears likely that the
meteorite fell earlier than the 12th century when the area was
largely unpopulated. Classification and mineralogy (D.
Badyukov, M. Nazarov, Vernad; J. Wasson, UCLA): the Dronino
iron is an ataxite containing sulfide inclusions (~10 vol.%) and
consisting of kamacite (7.0±0.5 wt% Ni and 0.75 wt% Co) and
rare taenite (26.5±0.5 wt% Ni and 0.35 wt% Co) as elongated
precipitates (1-3 µm in size) which form linear and banded
textures; sulfide inclusions (up to a few mm in size) rounded and
elongated along the banding; accessories are chromite and Fe
phosphate (graftonite?); no phosphide was found and P is not
detectable in metal with EMP; INAA data: Ni 98.1, Co 5.54
(mg/g), Cr 37, Cu 32, Ga <0.3, As 3.52, W 0.38, Ir 1.68 ppm, Au
0.284 (µg/g); the meteorite is most close to IVA irons in Ni, Ir
and the low P but the low Au and Ga contents distinguish the
Dronino element pattern from that of all known iron meteorite
groups. Dronino meteorite fragments are heavily weathered and
covered with rust 1-3 cm thick. Sulfide nodules are surrounded
by Fe hydroxides, which replace metal. Troilite of the nodules is
commonly replaced with unknown Fe,Ni sulfides. Specimens:
type specimen 700 kg including the largest 250 kg piece Vernad.
