Green, C. E., 2019. Investigating the origin of a Greenland ice core geochemical anomaly near the Bølling-Allerød/Younger Dryas boundary (Doctoral dissertation, Durham University). http://etheses.dur.ac.uk/13490/ http://etheses.dur.ac.uk/13490/1/C_Green_thesis_final_CORRECTIONS.pdf Green (2019) noted: "The source of a platinum peak identified in the Greenland Ice Sheet Project 2 (GISP2) ice core associated with high platinum/iridium (Pt/Ir) and platinum/aluminium (Pt/Al) ratios, and previous research attributed the anomaly to an unusual iron-rich Ir-poor meteorite impact." Green (2019) concluded: I. the Laacher See eruption is not the Pt spike source because: A. the Laacher See tephra has low Pt concentrations, B. the Laacher See tephra’s geochemical ratios are dissimilar to the GISP2 Pt spike and C. conversion of the Pt spike timing to the newest ice core age-depth model shows a chronological offset of ~60 years between the two events. II. The event resulting in the Pt spike occurred ~60 years after GS-1 cooling, and was therefore not the primary trigger. III. and the Pt spike origin is interpreted as either: A. a noncataclysmic impact of an undiscovered iron meteorite B. or an unidentified Pt-rich volcanic eruption contemporaneous with the anomaly, whose aerosol fractionated in the atmosphere or ice.

Is this not what i think it is? Certainly appears to me to be a microtektite. It is about 3/16 of an inch in length. I have place a sliver of pet wood to point it out. I have left it in the original matrix to better show what's going on......have i went crazy or is that not Spherules in that matrix here and there w/ it too?!?! And what's up w/ that unidentified black striated tubular shaped object there in the matrix? Sometimes volcanic micro glass (from pyroclastic debris?) Can resemble an impact Tektite (especially to my untrained eye! ), so i don't know perhaps this stuff could be from an eruption? I do have to ask one thing, and i beg your pardon....please don't ask me specifically where i'm recovering this material right now. I want to say badly, but i just can't presently...but in the future i promise to. It certainly is late Cretaceous from West Tennessee. As far as i can find out, this material has been unknown until now.....if it's what i'm thinking it is. I am also gonna post a couple pics of what i'm thinking will be Tektites, they are out of the matrix, so the shapes can be made alittle better....if they aren't good enough resolution, forgive me, they are somewhere around 1/2 the size of the one in the matrix(or alittle larger), & i am limited w/ the resolution of my phone. One of em reminds me of a lil' Bananna. so whatcha think....am i a complete fool, or maybe here is some evidence of deep impact/volcanic eruption?
