Influence of mineral composition of rocks on carbonate analysis results

By the example of Devonian terrigenous sediments with a high content of chamosite the correctness of the carbonate analysis results is considered. Comparison of results of researches of mineral and chemical composition is given by various methods, mathematical (statistical) data processing is executed. It is established that almost all magnesium and an essential part of iron occur from soluble silicates while processing HCl.
