On some tuffites of Southern Kalba
Authors:
Abstract
The existing petrographic classification defines tuffites as complex rocks with pyroclastic material and, quantitatively subordinate to it, normal sedimentary material. The content of the latter is most often specified in the range of 10‑15%. Such a peculiar composition of tuffites results from the specific conditions of their formation, when the products of volcanic eruptions and sedimentary, most often clastic material accumulate simultaneously in a water basin, mixing with each other. Naturally, organic remains, important to the geologist and usually of little importance in the rock composition, may also be found in the composition of such a rock.
