"KEY POINTS
• Basalts and pebbly to cobbly sandstones have been dredged from the Fairway Ridge, Coral Sea
• Dating of the rocks and interpretation of magnetic anomalies allow mapping of major geological units across North Zealandia
• This work completes offshore reconnaissance geological mapping of the entire 5 million square km Zealandia continent…”

Just spending November counting all the little bits in #medieval #limemortar from #Stavanger #Cathedral. There are a lot of them. #yolo #pointcounting #petrography #geology
