摘要
本文概述了煤形成温度的研究现状，探讨了湘中涟源地穹测水组、尤潭组煤的热演化史。利用ＬＯＭ法同时参考其它测温结果，计算了研究区各煤级的形成温度，并认为在各种受热条件下（深成热、区域岩浆热等），如果受热时间相差不大，形成同一煤级的温度是差别不大的。
First,a brief introduction for the study of coal ranks metamorphic temperatures is made.Then,the coal thermal history of the Ceshui and the Longtan formation is discussed.Next,the coal ranks metamorphic temperatures are determined in the area by using LOM method combining with studying others temperature results.Finally,it may be concluded that the difference between metamorphic temperature for the same coal ranks was negligible under various kinds of thermal conditions(the plutonic heat,the regional magmatic heat and so on) if heating time was approximate identical.
