Cave Exploration and Water Supplies in Java

Karstic (limestone) landscapes.
20% of the world’s population live on limestone.
1/4 of humanity depend on water from karstic aquifers.

Prof. Tim Atkinson explains the work he participated in to explore the karstic cave systems of Java, in order to provide potential sources of water for the local people, essential in the dry season.

A video of the talk can be viewed on the Members page.

Dolomite

Precambrian dolomite: detectable diagensis under the seabed

Prof. Ian Fairchild (TVGS President) introduces the many facets of dolomite (carbonate in which some of the calcium is replaced by magnesium). In particular he provides the evidence of dolomite in marine sediments, formed in the Precambrian in the midst of one of the hypothesised Snowball Earth glaciations and, how this is at odds with the idea the planet was completely under a thick cover of ice at the time.
