Hadamengou gold deposit in Inner Science Frontiers,2015,22(1):223-237
Abstract:The Hadamengou Gold Deposit in Inner Mongolia is so far the largest gold deposit,with superlarge
gold mineralization has no definite selectivity on lithology,however,it is mainly controlled by fold
and fault -forming fluids are mainly originated from the deep source,and are accumulated
within the favorable zones of tectonic expansion forming the ore- shows that,the mechanical
property of the structural deformation in this area had been evolved from plastic to brittle since the beginning,
and the scale of deformation is from small to and shearing deformations were formed
simultaneously or alternatively during the are four periods(or times)of intensive folding and
shearing in this area,and the main ore-forming and ore-controlling structures are formed during these periods.
During the first period,the rocks showed strong rheological the foldings developed are
characterized by low amplitude and small scale plastic rheomorphic are thickened in hinge zone and
thinned in the l
