An Introduction to Physical Geography
Lopolith : Lopolith is concordant igneous body found between two layers of the
rocks. Its shape is just reverse of laccolith. When magma is accumulated in
synclinal depression formed between two horizontal layers at the time of
unsuccessful ...

United States Geological Survey Professional Paper
Grout 64 considers the subsidence of the roof of the Duluth gabbro laccolith or
lopolith a factor in the formation of the Lake Superior syncline. Hotchkiss 65
likewise considers the origin of the syncline to be associated with the igneous
activity.

Geological Survey Professional Paper
The lower part of the Keweenawan is invaded by mafic intrusives, the largest
being the Duluth Complex northwest of Lake Superior, a lopolith 150 mi (240 km)
long and as much as 50,000 ft (15,000 m) thick near its center, injected near the ...

Palaeoproterozoic Supercontinents and Global Evolution
The intrusive relationships between the lopolith and country rocks are manifested
in the recrystallization and formation of hornfels at the exocontact zone, and in
the presence of schist and effusive xenoliths in the lopolith rocks. The Imandra ...

Precambrian Ore Deposits of the East European and Siberian ...
Sviridenko (1963) discovered coppernickel ores at the base of the lopolith, which
were subsequently studied in detail (Sviridenko et al., 1975, 1978). This pluton
has similarities with such ore-bearing layered intrusions as Zlatogorsk, Sudbury,
...

The Basics of Earth Science
The second type of batholiths is lopoliths (in Greek lopolith means "saucer").
They may also be lenticular-shaped, as are laccoliths, but they are sunken in
their central part due to the sagging of the underlying country rock. Lopoliths can
be rich ...

Earth Materials: Introduction to Mineralogy and Petrology
Lopoliths A lopolith (lopas is Greek for “shallow basin”) is a large saucershaped
intrusion, which can have a diameter of hundreds of kilometers. The Bushveld
Complex in South Africa, the largest known lopolith, has a diameter of about 300

Geology of Titanium-mineral Deposits
Schematic relation of Tellnes and Storgangen deposits and base of Bjerkreim-
Sokndal lopolith in NW-SE cross section. Restoration of the latter two to nearly
horizontal rotates the Tellnes body to nearly vertical, with a nearly horizontal ...

Stillwater Igneous Complex, Montana a Quantitative ...
The mechanics Of intrusion of diabase sills below the floor of the lopolith and the
chemical relations of the sills to the Bushveld differentiation sequence can also
be accounted for by the reasoning of the last paragraph (Fig. 33). The lowest sill ...

B097: Discovery and geology of the Desert Peak geothermal ...
The depositional and structural history of the lopolith is complex. Rocks of the
lopolith include intrusives ranging from gabbro to diorite in composition as well
as comagmatic extrusive units of basalt. The gabbro complex intruded a syn-
tectonic ...
