Diamicton facies in the vicinity of Duhlata cave, Bosnek karst region, Southwestern Bulgaria

open access: yesReview of the Bulgarian Geological Society, 2021
Karst caverns in the Upper Triassic dolostones of the Rusinovdel Formation are filled with allochthonous clastics (brecciaconglomerates with maximum boulder size) and locally with speleothems (flowstones). Deposition of the former (diamicton facies) by debris flows resulted from extreme flood events along the upper reaches of Struma river. The polymict
