strata-bound

All these felsic units record strata-bound albitisation, probably attributable to early, sea-floor hydrothermal activity.

Most fractures in core, even the dissolution slots, are strata-bound, but vertical interconnectivity is enhanced by faults.

Analysis of seismic reflection data is an invaluable tool for understanding the geological structure of strata-bound or layered ore deposits.

Beitler describes them as hollow "subhorizontal planar strata-bound pipes" and "vertical pipes."

Sulphate is considered to have been a major source of sulphide in strata-bound and stratiform base-metal sulphide deposits.

Of five breccia types recognized, the strata-bound, gold-bearing, and sulphide-rich breccias found at Knight Bay are economically the most important.

Strata-bound deposits include iron ores in the Dogger layer of the foothill zone and uranium near Müllenbach/Baden-Baden.

Historically, copper-silver mineralization in the area has been strata-bound and sub-horizontal; if this were the case, true widths would be close to core lengths in a vertical hole.

Mechanical reworking of older strata-bound copper deposits is indicated by significant copper content in clasts eroded from older rocks of the northeastern Mackenzie Mountains.

In the Wessels mine in Northern Cape Province of South Africa, sugilite is mined from a strata-bound manganese deposit.

Field and petrologic studies indicate that the strata-bound nickeliferous sulfide deposits of Jabal Mardah were formed contemporaneously with sedimentation of an active spreading ridge.

Massive baryte up to 25m thick outcrops along ridge-tops over several kilometres and is strata-bound in a thin, steep easterly-dipping, dolomitised limestone within a shale package of Carboniferous age.

Thin tourmaline-rich layers closely associated with strata-bound tungsten mineralization occur in layered amphibolites and metasediments of the Archaean Malene supracrustals in West Greenland.

The strata-bound Cu–Fe–S mineralization of the Lower Proterozoic Dunphy Formation forms the largest known sediment-hosted copper deposit of the Labrador Trough.

Cassiterite is associated with chloritic alteration and occurs as subhedral to euhedral grains, acicular needles, and colloform layers in veins in meta-argillite and as strata-bound disseminations in metawacke.

It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper.

The Duck Pond tin prospect is a vein- and strata-bound cassiterite prospect that is located 2 km west of the East Kemptville open-pit tin mine in southwestern Nova Scotia.
