简介：上面的三叠纪的Xujiahe()在四川的形成()盆，西南中国为盆规模沙免职是特殊的。这相对稀罕的沉积现象很好没被解释。这里，我们由讨论沉积框架和概念的模型处理了这个问题。沉积设定的分析暗示盆在免职期间收到了违反。它有多重起源供应和河网络，作为被在包括北方，东方和南方的多重方向的oldlands包围。因此，盆被沿海、广泛地开、浅的湖的免职通常在晚三叠纪的Xujiahe时期期间描绘。这类似于现代著名Poyang()湖。因此，我们与类似物在Xujiahe时期期间调查了框架和四川盆的概念的模型到波伊昂·莱克。结果证明免职的概念的模型能被划分成transgressive和回归的阶段。形成的第一，第三和第五个成员在transgressive舞台，存款被岸和浅湖的泥统治。相反，免职在回归的阶段期间主要具有编织的河隧道沙存款，主要包括形成的第二，第四和第六个成员。扔在的沙因为侧面的移植并且十字的前面的移动，几乎，全部盆编织的河联网。短、快速的违反和相对长的回归的多重引申对盆规模沙免职有益。因此，编织的河的主要隧道和它的extensional区域为烃水库的发展是有利的。这提供实际意义给水库评估和探索。另外，结果也在学习区域认为相对特殊的沉积现象正当并且可以也为在其它地方理解大规模沙免职有含意。
