Analysis of organic acid salts of marine carbonate rocks in Tarim Basin
摘要
Abstract
A method was developed for the determination of the organic acid salts of marine carbonate rocks in Tarim Basin by the thermogravimetric/differential thermal (TG/DTA), infrared spectroscopy (IR) and gas chromatography/mass spectrometry (GC/MS).By analyzing the guide sample such as the stearic acid, the magnesium stearate, the calcium stearate and the calcium carbonate by TG/DTA, the temperature range where the organic acid was gasificated while the organic acid salt wasn't gasificated were defined, and thereby the experimental procedures for separating and extracting the organic acid salt from the carbonatite rock was designed.The results show that the organic acid salt exists in carbonatite rock by using the infrared spectroscopy and gas chromatography/mass spectrometry. The quantity of the organic acid salts of marine carbonate rocks in Tarim Basin is insignificantly correlated with the carbonate content of samples, but it is correlated with the types of sedimentary facies of samples, namely relative enrichment of the organic acid salts in sedimentary strata of the slope facies sedimentary environment.关键词
