The golden age of exploration

This is an extract for the Black Country Geological Society newsletter. The end of the nineteenth and beginning of the twentieth centuries can be regarded as the golden age of polar exploration and there was great interest in Antarctica, both from the British and Norwegians. There were many expeditions culminating in Amundsen reaching the South [...]

Snowball Earth – The argument against…

In last week’s blog I outlined the evidence put forward for a worldwide glaciation in the Neoproterozoic, supported by geophysical and geochemical evidence. However, as with all ground breaking developments, other geologists look at the exposures and geophysical data and come to rather different conclusions. The basis of the idea is generated by the Neoproterozoic [...]

The geologists gathered excitedly at the first quarry, where Dr Neville Hollingworth was waiting to brief us about the local geology and what wonders we may find. Finally everyone arrived and I anxiously listened [...]
