Abstract

In river channels of NW Crimean Mountains the petrographic composition of alluvium is in close connection with the geology of the area. When a river crosses a zone of a certain solid rock the percentage of those rocks gravel noticeably increases. Another controlling factor is the rock resistance - debris of less resistant rocks (marl, clay bolls) are weared out within a few kilometres and form suspended component of alluvium. Only gravels of most resistant rocks - Upper Jurassic limestones - caome all the way from the river head and its content reaches 80 to 90% of the total alluvium volume near the mouth. - (L'Ed.)
