Feature of tectonically deformed coal and relation with gas outburst 構(gòu)造煤特征及其與瓦斯突出危險(xiǎn)性的關(guān)系
tectonically, the tectonic units consist of the gezu-xagquka suture zone and sangxuang-nagqu-midika slab in the surveyed area 構(gòu)造方面,構(gòu)造單元表現(xiàn)為各組下秋卡結(jié)合帶和桑雄那曲麥地卡板片的構(gòu)造格局;新發(fā)現(xiàn)達(dá)仁鄉(xiāng)奪列蛇綠巖體。
Filling sections of mesozoic-cenozoic tectonically active basins in china can generally be divided into five ordered, correlatable sequence stratigraphic units 摘要中國(guó)中、新生代構(gòu)造相對(duì)活動(dòng)的斷陷或陸內(nèi)前陸盆地充填序列一般可劃分出5個(gè)級(jí)別具有地層對(duì)比意義的層序地層單元。
These studies, therefore, suggest that the songsugou peridotite is not a tectonic massif of the upper mantle but a ultramafic magmatic rock body crystallized in deep crust and tectonically emplaced in the upper crust 從而證明了松樹(shù)溝橄欖巖體并不是上地幔巖石的殘片,而是由巖漿在深部地殼環(huán)境下結(jié)晶而成并以固態(tài)構(gòu)造侵位于地殼的上部。
Comprehensive analysis by combination of basin tectonism during basin formation and evolution with the basin filling and reforming is the key to reveal the configuration of depositional systems and the source, reservoir and seal in the inland tectonically active basins 摘要結(jié)合盆地形成演化過(guò)程中各種構(gòu)造作用與盆地沉積充填和改造過(guò)程的成因分析,是揭示內(nèi)陸構(gòu)造活動(dòng)盆地沉積體系域時(shí)空配置和生儲(chǔ)蓋發(fā)育分布的重要基礎(chǔ)。
The weishan-yongping copper-gold-polymetallic mineralization district in yunnan is tectonically located in the southern part of lanping basin in the middle part of changdu-simao block between lanchangjiang fault and jinshajiang-ailaoshan fault . more than 140 deposits and occurrences of gold, copper ( cobalt ), stibium, mercury, lead, zinc, iron etc . have been found in the area studied, and there are 4 medium-sized deposits among them 云南巍山-永平銅金多金屬礦化集中區(qū)位于瀾滄江大斷裂與金沙江大斷裂、哀牢山大斷裂之間的昌都-思茅中間地塊中部的蘭坪盆地的南段,礦化集中區(qū)內(nèi)目前已發(fā)現(xiàn)金、銅(鈷)、銻、汞、鉛、鋅、鐵等各種金屬礦床(點(diǎn))140處,其中達(dá)中型規(guī)模的礦床有4個(gè)。
The study areas are located in the jinshajiang zone, nw yunnan and sw part of the shizong-mile zone ( jianshui ), se yunnan respectively, and tectonically belong to the east part of the paleo-tethys tectonic domain . the jinshajiang zone in nw yunnan was a joint terrain between the yangtze and the gondwana blocks, and the shizong-mile zone delineates a suture line between the yangtze and cathaysian blocks 研究區(qū)分別位于滇西北金沙江帶和滇東南師宗-彌勒帶西南段建水地區(qū),構(gòu)造上位于古特提斯構(gòu)造域的東段,其中滇西北金沙江帶是揚(yáng)子陸塊與岡瓦納陸塊的交匯部位,而師宗-彌勒帶則分隔了揚(yáng)子陸塊與華夏陸塊。
