Such as in Gold Basin and > the Atacama desert, each place has been hunted very well and for > a period of several years. Probably a combination of factors working here: the use of metal detectors as the primary detection means coupled with the larger average size of L-chondrites vs. H-chondrites. (Plot of 10000+ Antarctic ordinary chondrites' mass histogram sent to Mark). If you look at the statistics for Lucerne Valley, Harper, Superior Valley, Silver and Cuddeback, you'll see that H's and L's are about evenly distributed, with H's slightly favored. --Rob ------_=_NextPart_001_01C3C521.2AA2BAEA Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 5.00.3810.1700" name=3DGENERATOR></HEAD> <BODY=20 style=3D"BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; = BORDER-RIGHT: medium none; BORDER-TOP: medium none; FONT: 10pt = verdana"><FONT=20 face=3Dverdana> <DIV><SPAN class=3D064282804-18122003>Hi Mark and List,</SPAN></DIV> <DIV><SPAN class=3D064282804-18122003></SPAN> </DIV> <DIV><SPAN class=3D064282804-18122003>> </SPAN>Another interesting = note on=20 multiple meteorite find area's is the habit<SPAN=20 class=3D064282804-18122003> </SPAN></DIV> <DIV><SPAN class=3D064282804-18122003>></SPAN> for the multiple = finds to be L=20 chondrites.
