摘要
“黔中隆起”,因袭罗绳武原用名称;“黔南坳陷”,系笔者等1958年所创。本文试将“黔中隆起”、“黔南坳陷”调整改组,从新划分构造单元格局,即以“黔中深断裂”为界,其北为“川南黔北构造地层地体”;其南为“黔南构造地层地体”。“黔中隆起”南以“黔中深断裂”为界,北以华蓥山深断裂为界,西以垭都、紫云深断裂为界;东边,贵州境内以白露断裂及北东向断裂组西南端消失线为界;四川境内以南川、涪陵、丰都为界。 笔者对“火烘型”泥盆系沉积构造控制因素、生物礁成生环境……等作了反思与补充修正。同时对贵州成矿条件、控矿因素强调以断裂为主,沉积古地理次之,岩浆活动、热液浸染、风化淋滤……等又次之,相互融合渗透。
The geological term,Central Guizhou Uplift,was named by Prof. Luo Shengwu,while the term, Southern Guizhou Depression,was named by the author et al in 1958 only for the purpose of serving production ,so its meaning,internal structure,tectonic framework,etc. were not studied in detail. As the tectonics theory is developed,the techniques of looking for minerals are improved,the tectonic unit diversions are getting complicated day by day and different viewpoints of different schools of tectonics appears,in recent years,the author ,from the viewpoint of geosuture movement and terrene theory,has made further researches on Central Guizhou Uplift and Southern Guizhou Depression and redivided the tectonic untis,that is ,the Central Guizhou Deep Fault is regared as a boundary ,on whose north is the tectonic stratigraphic terrenes of Southern Sichuan and Northern Guizhou and on whose south is the tectonic stratigraphic terrene of Southern Guizhou . In Guizhou ,the former range is demarcated by the Central Guizhou Deep Fault in the south ,the Huayingshan Deep Fault in the north ,the Yadu-Ziyun Deep Fault in the west and the Bailu Fault and the disappearance of the SW end of the NE Formation Fault in the east, the range is also demarcated by Nanchuan ,Fuling and Fungdu , including a bunch of depressional foldings in Eastern Sichuan and its secondary tectonic units in Sichuan and a bunch of early palaeozoic depressional foldings in Tangzi-Bijie and the northern part of a bunch of early palaeozoic arch fault foldings in Central Guizhou . The latter range is demarcated by the Central Guizhou Deep Fault in the north , the Kaiyuan-Pingtang Hidden Deep Fault in the south , the Yadu-Ziyun Deep Fault in the west and the Songtao-Dushan Deep Fault in the east,including a bunch of palaeodepressional folded faults in Southern Guizhou and the southern part of a bunch of early palaeozoic arch fault foldings in Central Guizhou . The adjacent areas of the two ranges are Central Sichuan tectonic stratigraphical terrenes , Eastern Yunnan and Western Guangxi terrenes, Northrn Viet Nam and Western Guangxi tectonic stratigraphical terrenes ,Xuefeng terrene and adjacent tectonic stratigraphical terrenes of Hunan ,Hubei ,Sichuan and Guizhou .
The author has also reconsidered ,supplemented and revised the Huoheng type sedmentary tectonic controlling factor of Devonian and bioherm creating environment ,etc. In addition ,the author has dealt with the mineralizing conditions and ore -controlling factors,pointing out that in these conditions and factors faults are main and sedimentary palaeogeography , magma activities ,hot liquid infections , weathering and leaching ,etc. are secondary.
