IEAX-1D Hand Sample

Item

Title
IEAX-1D Hand Sample
Description
Overall there is a dark gray groundmass with multiple larger inclusions, varying in color, along with smaller lighter color specks of inclusions and heavily fractured. The groundmass is very dark gray to black with heavy vesiculation on one portion of the sample, even coloration throughout the sample, and fractures filled with sediment. The large white to light gray inclusion is up to three centimeters in diameter, heavily fractured and possibly cleaved, some yellow discoloration. The orange clasts look similar to the yellow discoloration found in the large inclusion, but more concentrated in color. There are small pockets of melt coming through these smaller inclusions, implying some disequilibrium with the inclusion and the melt. There are also some subhedral phenocrysts of minerals, most likely feldspars and smaller pieces of the larger white clast.
