In March I had the pleasure of accompanying the PhD candidate Edafe Ominigbo (School of Earth and Atmospheric Sciences, Queensland University of Technology) to Kalimantan, which is the Indonesian part of the island of Borneo. We were there to collect mafic rocks as part of his study. I know very little about igneous petrography (I […]
Out of Time
How the newly published paper “Constraints from lamprophyre petrogenesis on the timing of Eocene lithospheric thinning and associated rifting of Borneo and Sulawesi” (Murphy et al., 2024) came to be has an interesting history. Well, to me anyway. If we take the Way Back Machine* to the mid-1980s, when I was doing my PhD field […]
New Paper: Evaluation of peat character in Kutai lakes area, Kalimantan Timur, Indonesia
Ever get that sinking feeling? Well, if you were standing in the Kutai lakes area in central Borneo you’d be right to think so. And its not just because it is full of peat and wetlands. Located about 100 km from the nearest coast and surrounded by low, heavily vegetated hills, that border on becoming […]
Field Work in the Senakin Peninsula: Part III – NEW PAPER
The fruits – as they say – had finally ripened and what fell off the tree? A paper of course*. A nice fat, juicy paper about those lovely Eocene-age volcanics that lie within the Senakin Peninsula. After a couple of decades wondering when someone would publish on the basalts and volcaniclastic sediments in Kalimantan Selatan […]
Field Work in the Senakin Peninsula: Part II- Finding Volcanics
The speedboat skipped from wave to wave effortlessly; Tanjung Dewa was on our left and then it was gone. A head of us I could see the Senakin Peninsula, its dark forests tangled with cloud. The chill morning air made me smile. My three colleagues, Mr Mike Friederich, Prof Hendra Amijaya and Dr Ferian Anggara, […]
Part III – The Miocene Coal-Bearing Section: Geological Time Travel in East Kalimantan. The Society for Organic Petrology Field Trip
Geological Time Travel in East Kalimantan (Borneo): Part I – Fresh Water Lakes
We sped across the surface of Lake Semayang with the bottom only inches below us. Using traditional long boats – with light but powerful engines – twenty-seven of us were headed for Semayang village, on the north central ‘coast’ of the lake. We were there as part of a geological field trip examining modern environments […]
