利用单边封闭的蜡泥塑料来进行平面压陷实验以帮助我们去了解东亚限定的陆间形变和走向—滑动断层的演化。一些大型左旋走向—滑动断层曾不断活化,主体上是同时的。实验显示印度向亚洲插入曾经旋转了(≈25°),并且在碰撞的前二、三千万年里沿红河左旋断层使印度支那向东南挤压了(≈800公里)。该过程能说明南中国海在晚中新世前张开的原因。挤压构造北移,促动阿尔金塔格断层成为第二条主要的左旋断层,并使华南向东移动数百公里。事件发生后,印度支那保持顺时针转动(多达40°),而红河和它南面的走向—滑动断层则作反方向运动。莫圭盆地和安达曼海的张开(直到现在)看来也是挤压的简单运动结果。中国东北部和云南现代裂谷可看出类似于南中国海和安达曼海的初期。若以我们实验为指南,像泰国海湾(暹罗湾——译者)等沉积盆地的其它第三纪构造现象可说明是碰撞的结果。实验还预示有一个重要的左旋走向滑动断层和裂谷系将扩展穿过天山、蒙古和贝加尔而延至鄂霍茨克海。
Plane sag experiments were performed using unilateral closed wax plastic to help us understand the terrestrial deformation and strike-to-slip transition in East Asia. Some large-scale left-lateral strike-slip faults have been continuously activated and are mainly simultaneous. Experiments have shown that India had rotated (≈25 °) to Asia and squeezed Indochina southeast (≈800 km) along the Red River LEF in the first two or 30 million years of the collision. This process explains why the South China Sea opened before the late Miocene. The crust moved northward, activating the Arguntag Fault as the second major left-lateral fault and moving south China eastwards for hundreds of kilometers. After the incident, Indo-China kept turning clockwise (up to 40 °), while the strike of the Red River and its south-slip fault in the reverse direction. The opening up to the Maugu Basin and the Andaman Sea (until now) also seems to be the result of a simple squeeze. The early rifts similar to the South China Sea and the Andaman Sea can be seen in northeastern China and Yunnan Rift Valley. Other tectonic phenomena in sedimentary basins such as the Gulf of Thailand (Gulf of Siam) may be the result of collisions, guided by our experiments. Experiments also indicate that an important left-lateral strike-slip and rift system will extend beyond the Tien Shan, Mongolia and Baikal to the Sea of Okhotsk.
