SUMMARY:AGM: Himalayan Geology
DESCRIPTION:AGM\n\nThe society's AGM will be transacted as swiftly as possi
 ble.\n\nFollowing the AGM we have a talk\n\nUnravelling Himalayan Geology 
 through time\n\n[caption id="attachment_4981" align="alignnone" width="420

 will take us through the mountains and explain how scientists worked out t
 heir evolution\; how work undertaken in the 19th C. by the Great Trigonome
 trical Survey of the British Raj gave us an understanding of the nature of
  the roots of the mountain chain\; how engineers of the East Inda Company 
 searching in Siwaliks sandstones made discoveries of sabre-tooth tigers th
 at helped Darwin with his theory of evolution\; how Sir Richard Strachey\,
  undertaking the first geological traverse of the mountain chain and obser
 ving dramatic folds and faults\, realised that great compressive forces ha
 d been at work\; how members of the Geological Survey of India\, recording
  the continent’s coal deposits\, worked out that India had once been par
 t of a southern continent which they called Gondwana\; how the Survey geol
 ogists also recorded fossil evidence indicating the rocks of the mountains
  had once been under the sea\; how the Swiss brought understanding of napp
 es and thrusts to the Himalaya and how they recognised ophiolites in the n
 orthern regions of the mountain chain\, indicating the former existence of
  an ocean\, the dense foundations of which are now crumpled up in the heig
 hts\; and finally how British scientists worked out how inverted isograds 
 (upside down metamorphic gradients) were the result of ‘channel flow’ 
 (partial melting and ductile flow in the mid crust) and how lateral contra
 ction of the mountain chain was achieved by stacking of thrust sheets. Thr
 ough these observations and deductions they came to understand a classic e
 xample of a continent-continent collisional plate margin.\n\nDanny Clark-L
 owes is a geologist with over 45 years’ experience who has worked in num
 erous locations around the world including arctic east Siberia. He worked 
 for a number of oil companies\, including Shell\, before founding Nubian C
 onsulting to focus on the geology of North Africa\, particularly Libya. He
  is the author of numerous scientific publications and books. He is a keen
  mountaineer who has climbed in the Swiss Alps and in the Himalayas where 
 he has led many geological and trekking trips over the last seven years. H
 is book ‘A Geological Field Guide to the Himalaya\, in India\, Nepal\, B
 hutan and Tibet’ was published in November 2022 by the Geologists’ Ass
 ociation (Guide No 76). He is also active with the U3A (University of the 
 Third Age) with which he runs Geology Field Trips in the Lake District.\n\
