滇东北地区煤的变质程度具有与区内构造-成矿亚带一致的分带变化规律,其中以金牛厂-矿山厂亚带煤的变质程度最高,往北变质程度逐渐降低,往南变质程度则快速降低。同时探讨了其成因,认为峨眉山玄武岩浆的喷溢活动对区内煤变质程度的整体... 滇东北地区煤的变质程度具有与区内构造-成矿亚带一致的分带变化规律,其中以金牛厂-矿山厂亚带煤的变质程度最高,往北变质程度逐渐降低,往南变质程度则快速降低。同时探讨了其成因,认为峨眉山玄武岩浆的喷溢活动对区内煤变质程度的整体提高起着重要作用,而煤变质的分带性则可能与热液(水)变质作用有关。 展开更多

Based on statistical analysis on morphological data of nebkhas surveyed in the Hotan River Basin,Xinjiang, the changing regularity and characters of nebkhas’ morphology in different development stageshave been discussed. Results indicate that there exist better correlation among length, width and altitudeof all kinds of nebkhas, but there are certain various shape characters in different nebkhas and the sametype of nebkhas in differential development stages. On account of analysis on mathematical imitation ofnebkhas’ shape characters, regional ecological environmental and aeolian characters, the development ofthe nebkha can be divided into a growing stage, a stabilizing stage and a declining stage. 展开更多
