This form should be filled out and sent to  The Meteoritical Society  for official recognition

A new Associate Editor for Northwest Africa meteorites, Caroline Smith will be replacing outgoing AE Mike Zolensky.
During the transition period in 2005 October, the electronic submission form should not be used.
All questions should be directed to Harold Connolly


Proposed Name ......................................................................coordinates if known  eg... 44 26′ 00 N  87 38′ 00 E

City, County and Country (or area as in NWA; or place of purchase)

Find or Observed Fall: 
Date (day/month/year if known)

Classification (Class)  e.g., Achondrite (eucrite)

History : 
How the specimen was acquired and any visual or audible observations such as Fireball or smoke trail .


Physical characteristics:   Weight of total mass , the number of pieces,
and external characteristics such as fusion crust and color .

 
Petrography:

1. Name of the research that wrote the description and their  scientific institution ( in italics). 
 Use the abbreviations in http://tin.er.usgs.gov/meteor/MetBullAddresses.php or ARN Link or define a new one here. 
2. Describe the petrography only, no composition or interpretation. 
Stick to the empirical data
For example:   The sample is covered in approximately 65% fusion crust.
It contains olivine, pyroxene, Fe, Ni-metal and abundant (~80%) chondrules. 
The chondrules range in size from ~ 1mm in apparent diameter to 0.5 mm. 
The chondrule margins are clear and defined .
The stone contains a large variation in the textural types of chondrules including BO, PO, POP, and PP.
If it is metamorphic in nature, a breccia, contains abundant opaque phases such as carbon, numerous crack or micro-faults.

All such information should go into this section. Obviously, achondrite descriptions will be different from chondrites.
What is presented is just an example .


Geochemistry:
1. Name of this researcher and their
institute (in italics) if it is different from above
2. Give the composition of the major phases, trace element data, bulk analysis, isotopic data if available .
If possible how the data was obtained (e.g., EMP, ICP-MS, INAA, etc.). 
For such data, subheading should be underscored, such as Oxygen Isotopes
To report analytical data, use the following format: Si = 45.35, Mg = 36.45 (all in wt% or ppm or ppb) etc.

Again, no interpretation and stick to the empirical data. 
 
Classification: 
1.Name of classifier if different from anything listed above . 

2.Give the major classification with (type in parentheses)
e.g., Carbonaceous Chondrite (CR2)
3. Degree of shock .
4. Degree of weathering (W scheme can only be applied to ordinary chondrites) .
All others use no weathering categories but use terms such as minor, major etc. 
A new scheme exists for CK meteorites that can be used if desired.)


Specimens:
1.A total of grams of type sample and one thin section (if any) on deposit at institute   XYZ  .
Minimum required is 20 grams or 20% of mass whichever is smaller .
2.
List all masses and locations for all deposits .

eg.
Mr. G. J. Meteorite holds the main mass or an anonymous collector holds the main mass.
