Shatter Cones Impact Material K-Pg Boundary
Sciencemall-usa is an online science mall store that features shatter cones, impact material and KT, K-Pg boundary clay. These geological specimens are found at world meteorite, asteroid, and comet impact sites. So far the Earth Impact Database
lists 190 confirmed impact sites. Evidence for these impact sites varies. Some are found with shatter cones, others are not. Some impact sites have only the evidence of planar deformation features (pdf's) or stressed and deformed shocked quartz. Of these impact sites some are confirmed, others are suspected.
We have for sale professionally collected: shatter cones, impact material, tektites, microtektites, high pressure/temperature minerals, and KT or K/Pg boundary clay.
