John Cole Roberts is a Welsh geologist. His paper "Feather Fracture and the Mechanics of Rock Jointing" introduced the geological community to this newly identified and newly classified fracture patterning, along with its impact in terms of jointing structures. He announced it in the summer of 1961. It continues to be the definitive standard of feather fracture work. == Early life == Roberts was born in 1935 in South Wales, and grew up in the valleys surrounding the iron and steel town of Dowlais. He would have left school and started work in his mid teens, like the majority of young people of the time, had it not been for a school master, Ron Gethin, who realised his aptitude for earth sciences. The first boy to take geology to O-level and A-level in his district, Roberts studied at Swansea University (University of Wales), where he graduated and obtained his PhD in Geology, in 1961, for his thesis "Jointing and Minor Tectonics of the Neath Disturbance and Adjacent Areas". Roberts became an expert in the jointing and fracture science of the South Wales coalfields and in the geology of the areas around the Vale of Glamorgan and of the Gower Peninsula of Wales.〔 After receiving his doctorate, Roberts progressed into lecturing, initially at Aberystwyth University. There he met his future wife, Susan Davies (a mathematics undergraduate student). He later moved to Northern Ireland. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Cole Roberts」の詳細全文を読む スポンサード リンク
