MARCASITE IN BLACK SHALES—A MINERAL PROXY FOR …

pyrite framboids. Marcasite forms either clusters of equant euhedral grains (Fig. 3A) or aggregates of tabular crystals (Fig. 2A, B, C). These morphologies, as well as spearhead twinning and well developed cleavage (Fig. 3B), help to differentiate marcasite from pyrite under the petrographic microscope and the SEM (Ramdohr 1980; Bush et al. 2004).

MARCASITE (Iron Sulfide)

Marcasite is a polymorph of pyrite which means that it has the same chemistry as pyrite but a different structure and, therefore, different symmetry and crystal shapes. The marcasite/pyrite polymorh pair is probably the most famous polymorph pair next to the diamond / graphite pair. Adding to the confusion between marcasite and pyrite is the ...
