| 摘 要： | 以历史分析法为原则,对构造史、沉积埋藏史和热演化史作三位一体的研究,得出：鲁西南地区煤变质演化经历了4次构造发展阶段,形成了3种不同的地质历史模型;煤的热演化划分为均衡、差异和减缓3个阶段;深成变质作用具有普遍性、长期性和阶段性变化的特点,而区域岩浆热变质是一部分煤田煤级增高的主要原因。 |
| 关 键 词： | 煤变质演化 煤化作用模式 热演化史 深成变质作用 区域岩浆热变质 山东 |

| Abstract: | By the principle of historic analysis, this paper studies the histories of structure, depositional burial and thermal evolution history. The result shows that coal metamorphic evolution in Southwest Shandong underwent four stages of structural development, formed three different geologic history patterns. Coal thermal evolution is classified into three stages of balance, discrepancy and alleviation. Hypometamorphism is of long term development and periodic change characteristics and the telemagmatic thermal metamorphism is the main factor for increasing coal rank in part coalfield. |
| Keywords: | Southwest Shandong coal metamorphic evolution coalification pattern thermal evolution history hypometamorphism telemagmatic thermal metamorphism |
