秦岭祁连山昆仑山构造发展史与南北中国板块的拼合

TECTONIC HISTORY OF QINLING-QILIANSHAN-KUNLUNSHAN MOUNTAINS AND THE MATCHING OF BOTH SOUTH AND NORTH CHINESE PLATES

按秦岭祁连山昆仑山发展演化，中国大陆的形成可总结为3阶段板块拼贴“焊合”模型即：中元古代至新元古代早期，原始秦昆洋俯冲—消减，塔里木—华北古陆（北中国板块）与华南洋域新生陆壳（南中国板块）拼贴增生，形成原始中国古陆；震旦纪至志留纪，原始中国古陆裂解，秦祁海洋扩张—俯冲—消减，阿拉善—华北板块（北中国板块）与塔里木、柴达木、华南组成的联合板块（南中国板块）缝合统一，形成古中国板块，泥盆纪至三叠纪早期，古特提斯洋俯冲—消减，藏滇板块（基梅里大陆一部分）与古中国板块碰撞拼贴，滨邻古特提斯洋的中国大陆西南缘（秦祁昆地区）全面皱起，造就中国大陆轮廓；中生代以来，板内超长期继承性汇聚和滨西太平洋边缘构造带、新特提斯—喜马拉雅构造叠加、改造，造就现令中国大陆构造、地势。

According to development and evolution of Qinling - Qilianshan - Kunlunshan momtains , three developed stages of matching and" welding" model have been concluded for the formation of the Chinese concinent.1)In the period from the middle Proterozoic to the Late Proterozoic era,primary Qinling - Kunlun oceanic passed through subduction-consumption, matching and overgrouth between the Tarim-North China ancient land (North Chinese Plate) and the South China neo -continental crust(southern Chinese Plate),forming the primary Chinese ancient land;2)From Sinian to Silurian periods,as the primary Chinese ancient land splitting, the Qinling - Qilianshan ocean extension ~ subduction - consumption, Alashan - North China Plate (North Chinese Plate), Tarim, Chaidam and South China Plate, constituted the joint plate (South China Plate ) in unity, forming the ancient China Plate ;3)From the Devonian to early Tertiary period,as the old Tethys ocean subduction comsumption, the Tibet -Yunnan plate (part of the Jimeili continent)and the ancient China Plate collision and matching,the old Tethys ocean adjacent to the southwest margin of the China continent (Qinling -Qilianshan -Kunlun area)totally folded, thus shaping the outline of the China continent,Since the Mesozoic era, sequential convengence within the plate,marginal structures in the western Atlantic ocean and superimposition and reformation of the Neo ~ Tethys - Hi malayan structures have formed the present Chinese continental tectonic and landform.
