Of all the particles in a sedimentary basin, organics are arguably the most insightful. Think about it: they tell you how hot things got, millions and millions of years ago, and that is both within the basin at depth but also at the surface when they were deposited; they tell you what plants were evolving; […]
“Without data, you are just another asshole with an opinion”, said John Ferm standing at the blackboard, chalk in one hand and a cigar in the other with smoke swirling around his head (this was, after all, 1985). It’s a phrase John (my MSc and PhD advisor) would often use when we, his students, started […]
Though mostly overlooked by sedimentologists and climatologists coal provides highly detailed information on past climates and tectonics. In a recent paper* by myself and my colleagues (available Here) we take a look at a very thick (>40 m) coal of Early Cretaceous age in Inner Mongolia, near the borders with Russia and Mongolia. Using stable […]
Two geologists walk into a bar. The first orders a ‘Flaming Volcano’ (he’s a neo-tectonics/Quaternary guy). Without blinking an eye the bartender asks him what sort of rum he’d like. The second geologist orders a ‘Black Coal’ Stout (she is an organic petrologist). Everyone in the bar freezes then slowly slinks out the door …. […]
It was like jumping off the end of a pier into unknown depths with unknown dangers – but a quick calculation (in actuality lots of deep reflection) indicated that it was safe…-ish; nevertheless it was exhilarating. Thus, Cipher was born. In early September 2010 Cipher started trading and by late September we had our first […]
No, not a dinosaur. Not an asteroid. But some kind of climatic condition that was none-to-good for organic material. For a very very long time. Over the last year, my colleagues Prof Jian Shen and Prof Marvin Moroeng from China University of Mining and Technology (Xuzhou, China) and University of Johannesburg (South Africa), respectively, and […]
My father worked for the phone company all his life. Actually, that isn’t completely true. In 1943, during World War II, he joined the Marines, got married and managed not to get killed. After the war he returned to his job at the C&P Telephone Co., played around on boats in and around the Potomac […]
Thirty seconds seems like an incredibly short amount of time. But a lot of things can happen in thirty seconds. I had removed one of my gloves to turn the page in my field notebook to jot down some measurements on the coal we were sampling. It was a bad idea. In that short amount […]
The second year of this field trip saw us going up the southern Queensland coast looking at both the modern and ancient geological environments. The students are first and second years, from the School of Resources and Geosciences from Xuzhou, China and come for 15 days. In almost all cases this is the first time […]
The Hailaer Basin in Inner Mongolia, China has a lot of coal, mostly of Cretaceous age; some beds are over 40 m in thickness. Setting aside any of its economic uses, the scale of peat accumulation is phenomenal. The basin itself is tectonically dissected into coal fields ranging in size distribution from 20×80 km to 40×120 […]
