Abstract An irregular-layered or lenticular hydrothermal jaspilite layer occurs at
the green shale/carbonate rock boundary in the middle of the Tieling Formation
of the Mesoproterozoic Jixian System. At one outcrop there are, in the jaspilite.

U.S. Geological Survey professional paper
Jaspilite occurs in fragments in basal Goodrich Quartzite and is identical with
bedrock jaspilite, indicating that pre jaspilite iron oxide-chert rock existed as such
during the Negaunee-Goodrich erosion interval. In general, jaspilite is underlain
by ...

The Geological Record of Neoproterozoic Glaciations
Parallel-laminated facies hosting haematite-jaspilite are commonly interpreted as
interglacial or interstadial. but they might altematively represent maximum glacial
stages. when outlet glaciers were blocked by thick multi-annual sea ice ...

Pre-Cambrian Geology of North America
The fundamental ore and jaspilite appear to belong, stratigraphically, to the
Republic formation. Most of the jaspilite of the formation is of detrital origin, being
originally conglomerates, breccias, sands, and muds, which have been
subsequently ...

Jaspilite is a banded compact siliceous rock consisting of interbanded jasper (red
▷ chert) and ▷hematite. In Australia the term jaspilite was commonly applied to
Precambrian iron formations of Western Australia, but ▷ banded iron formation ...

Precambrian Banded-Iron-Formations
Kalyayev (1965) distinguishes three types of cherty ironformation: sedimentary,
volcanogenic-sedimentary, and the jaspilite subformation within the spilite-
diabase formation. The sedimentary jaspilite formation, the stratotype of which is
the ...

The strongest evidence that the jaspilite at Ishpeming and Negaunee is of
Republic age is the similar rock associations which the jaspilite here has with the
jaspilite known to belong to the Republic formation. The simplest explanation of
the ...
