Dear Meteorite collectors, I am in the process of working on the bulk mineralogy of Sutter’s Mill as determined by powder x-ray diffraction. I have run several samples now, including the pre-rain SM3, and found some interesting minerals. My big interest is in the clay mineralogy, the quantity and type in each sample I am arguing reflects degree of pre-terrestrial heating. I now have a relatively good dataset of samples (SM3,41,38,49,65,8,6,12,53), but would dearly like to run a few more. There seems to be some gaps in the data with regards to clay content and hence heating. I don’t know yet whether this gap reflects the fact that I have not looked at enough samples, or is real and is telling us that there are two groups of Sutter’s Mill - clay rich (mildly heated), and clay poor (heated to high temperature).
So, I am looking for small pieces of samples for my research. Ideally, I am looking for donations of small fragments - 100 mg would be perfect, though I can still work on samples in the 20 mg range. If anyone has samples available, then please feel free to email me. Thanks Laurence -------------------------------------------------------- Dr. Laurence A.J.
