Crustal Structure Of The Bhutanese Himalaya: New Insights From A Gravity Analysis In Western And Central Bhutan, Kinzang Duba
Crustal Structure Of The Bhutanese Himalaya: New Insights From A Gravity Analysis In Western And Central Bhutan, Kinzang Duba
MSU Graduate Theses
To expand the current understanding of lithospheric structure within Bhutan Himalaya, a detailed gravity survey was conducted for the first time along the all major roads within western and central Bhutan in 2015-2017. The acquired Bouguer gravity anomaly data were analyzed and interpreted using map methods (wavelength filtering and Euler deconvolution) which clearly indicate that there are substantial anomalies due to crustal density sources and a complex Himalayan geology. Four two-dimensional gravity models across the Himalayan tectonostratigraphic units were constructed to determine the crustal density structure using constraints from the geological and geophysical studies. The results support that the long …
