Stratabound Ore Deposits in the Andes
The contacts among hematitic strata are sharp and irregular in shape when
hematitic strata interstratify with chamosites and quartzites. Flaser lamination,
although not well developed, is a frequent feature. A similar process occurs with
massive ...

Similar hematitic alteration, also including epidote and sericite, accompanies
many copper ores that include gangue hematite and native copper, such as the
basalt-hosted, Cu-Ag veins (chalcocite) of Mamainse Point, Ontario (Richards
and ...

The gritty material is seen under the microscope to be probably tuffaceous,
consisting of subangular to angular grains of several kinds of lavas, both
andesltic and basaltic, cemented by a hematitic matrix. The mafic minerals are
entirely ...
