But I did note that one area of the strewnfield was more likely to produce pallasites than the other. But both were mixed and scattered over a very large area. There is in my mind no doubt that the two types are from the same meteoroid, and that Glorieta is a very unusual meteorite. I have in my collection one blue black fusion crusted 1.5 kg iron that has at least a dozen olivine crystals showing. Then I have three other solid irons of , 386 g.; 658 g. and 2,704 grams with no olivine. Externally they look nothing like the pallasite phase-- but excluding the sulfides and olivine the Fe-Ni composition is identical and ties together the two types.
