Dolomitization front geometry, fluid flow patterns, and the origin of massive dolomite: the Triassic Latemar buildup, northern Italy

Abstract

In this small carbonate buildup, 10 to 12 km3 in volume, transitions from limestone to dolomite are abrupt and crosscut depositional and early diagenetic features. Mapping has established that fractures and permeable beds were the "plumbing conduits' of the dolomitizing fluids, which altered 2 to 3 km3 of grainstones to sucrosic dolomite mosaics. -from Authors
