Breccia http://web.wm.edu/geology/virginia/provinces/Blueridge/fault_zone_lithology.html Photomicrograph of fault breccia in the Antietam Formation, Blue Ridge province. Breccias form when rocks are extensively fractured in fault zones and are cemented together when minerals precipitate in the cracks and fractures. Note the angular fragments (fr) of quartz sandstone in a matrix of fine-grained iron oxide cement (ic). Field of View 4 x 2.7 mm, Cross Polarized Light.

The word "pseudotachylite" was coined early in the 1900s to name a peculiar glassy rock that looks sort of like tachylite but isn't. Tachylite ("TAK-a-lite") is a basaltic glass A psuedotachylite is a frictionally generated melt rock http://www.gm.univ-montp2.fr/spip/spip.php?article761 GLG310 Structural Geology
