Allegan, H5

Allegan’s a historic American fall from 1899.  It’s a fairly typical H-chondrite, with moderate porosity and well-defined chondrules.

From Merrill and Stokes’ 1900 report:

Source: A new stony meteorite from Allegan, Michigan, and a new iron meteorite from Mart, Texas, by G.P. Merrill and H. N. Stokes.

These are two such fragments from the main mass, purchased from the collection of a deceased geologist in Michigan.  They came with original prints of the above paper and an original copy of Wirt Tassin’s 1909 paper on oldhamite in Allegan.
