Rock formation Guerilla Bay 格里拉湾岩石层风貌
Guerilla Bay rocks are some of the oldest rock formations on the east coast of Australia (Ordovician
period ~ 450 mya) . These were laid down possibly during an interval of subduction in the ancient
Pacific Ocean, before becoming part of the prehistoric Gondwana continent.
格里拉湾岩石是澳大利亚东海岸最古老的岩石，约形成于奥陶纪时期至4.5亿年前。其成因可能是：当时在古太平洋地壳运动过程中，某一板块沉到了另一板块之下，在移动间歇期，这些岩石沉积了下来，形成了现在的格里拉湾岩石，而没有成为史前冈瓦纳大陆的一部分。
