Halong Bay Geology: How Was Halong Bay Formed?

The limestone that is found in Halong Bay began forming during the Carboniferous period, around 340 million years ago. At this point, the Earth was much warmer and wetter than it is today, and due to large swamps carbonate sediment moved into the oceans. This resulted in the gradual hardening and thickening of the limestone over many millions ...

Geology of Vietnam - Wikipedia

Vietnam's mineral resources, apart from offshore oil and gas, include phosphate, coal, bauxite, base and precious metals, and a variety of industrial minerals. More than 5,000 mineral occurrences have been identified. Five broadly-defined metallogenic epochs have been recognised and, in general, the younger the setting the more abundant the deposits. Only a few are hosted by Precambrian rocks, principally iron, gold and graphite. The early to mid-Palaeozoic contains small deposits of iron ore, lead–zincand large de

List of karst areas - Wikipedia

Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. It has also been documented for weathering-resistant rocks, such as quartzite, given the right conditions. This is an incomplete list of the major karst landscape areas of the world.
