 Dave Green's microscope course
WhenThu, 2 March, 19:30 – 21:30
WhereThe Chantry, Thornbury. (map)
DescriptionRocks and Minerals under the Microscope.  This 10 week course aims to introduce you to the identification and description of rocks and their component minerals under the petrological microscope. This is a practical course, each participant will be provided with a microscope and a set of thin sections of rocks, and will work through a course at their own pace. Held at The Chantry, Thornbury. First meeting 7.30 – 9.30, Thurs 12th January until March 23rd (not Thurs 16th Feb) in the Buckingham Room. Max. numbers 20, “first come, first served” due to number of slide sets. Cost £75

 Bath Geol Soc Lecture - Gas, geothermal energy and gold

DescriptionGas, geothermal energy and gold: the Earth’s crust as a percolator Professor Tom Blenkinsop, School of Earth and Ocean Science, Cardiff University Assessment of Earth’s finite natural resources becomes an increasingly urgent task as they are depleted, yet demand continues to rise. "Peak resources", the time at which production starts to decline, may occur within a few decades for some critical metals and oil. New methods of resource evaluation take advantage of the fractal geometry of georesources. Lode gold deposits, geothermal wells and volcanoes, and conventional and unconventional gas wells all have fractal characteristics that can be assessed by these techniques. These seemingly disparate resources are connected, as they form by fluid fluxes through the crust. Their origin can be considered as a consequence of percolation, bringing a further armory of theory to bear on understanding their formation and distribution.
