Antarctic Natural Thermoluminescence Survey Database

The Antarctic natural TL database is organized by icefield. Explanations of column headings are listed below. Researchers who wish to obtain a hardcopy version of this database along with a complete set of reprints published by the Natural TL Survey Laboratory should contact either Derek Sears or Paul Benoit. The database contains data collected since the inception of the Natural TL Survey Laboratory in fall 1986 through November 1998. Click here for more background to the Antarctic Natural TL Survey.

* A major fall from a meteorite that had only recently become Earth-crossing.

Antarctic meteorites are identified by the three-letter abbreviation assigned by the curators at JSC for the location of the ice field and with a five-digit number with first two digits representing the field season for the collection.

Explanation of Column Headings in Database

Class. Chemical class H, L, LL for ordinary chondrites (OC if not further classified), CI, CM, CO, CV, CK, CR, for carbonaceous chondrites, and EH and EL for enstatite chondrites are given with petrologic type in the next column. Abbreviations for non-chondrite meteorites are Euc for eucrite, How for howardite, Dio for diogenite, Meso for mesosiderite, Lun for lunar meteorite, Mar for martian meteorite, and Ure for ureilite.

NTL. Natural thermoluminescence at 250C in the glow curve. The error quoted is the precision on the measurement calculated as the standard deviation on three measurements.

Wthg. Weathering category as determined by visual inspection of the hand specimen. A refers to minimal, B to intermediate, and C to considerable weathering.

Field. Name of the ice field where a region consists of several separate stranding surfaces. Allan Hills (Main, Nearwestern = Nearw, Farwestern = Farw), Lewis Cliff (Upper Ice Tongue [UIT], Lower Ice Tongue [LIT], Meteorite Moraine [MetMor], South Lewis Cliff [SLCliff], Upper Walcote Neve [UpWalNeve], Walcote Neve [WalNeve]; Upwall).

Pairing. Name of parent fragment in the case of meteorites that have been paired.

Mtot. Total mass recovered (in grams).

Msam. Mass used for thermoluminescence measurement (in milligrams).

TLS. Induced thermoluminescence sensititivity on a scale of Dhajala = 1.

Tp. Induced thermoluminescence peak temperature (oC).

Tw. Induced thermoluminescence peak width (oC).

AMN. Volume number and issue number in the Antarctic Meteorite Newsletter in which the data were originally published. In the case of non U.S. samples, the Meteoritical Bulletin (MB) number is given.
