Examples
-
In homogeneous rocks the tendency is to open clean-cut fissures; in friable rocks, zones of brecciation; in slates or schistose rocks, linked lenticular open spaces; -- these influences exhibiting themselves in miner's terms respectively in "well-defined fissure veins,"

-
Best results are from two of the four drillholes at Zone 4, where elevated gold values are associated with zones of brecciation and silicification.

-
The gold mineralization is structurally controlled and occurs in zones of quartz-sulphide veining and brecciation.
-
The drillhole is not expected to contain significant copper mineralization, however, the intense alteration and brecciation in the drillhole is encouraging and has provided a new impetus to test the associated geochemical anomalies.
-
These faults vary in width from a few meters up to 50 meters and consist of highly fractured and limonitic zones with varying amounts of silicification, brecciation and gold.
-
Drill hole CBX006 showed strong evidence of an extensive disruptive geological event associated with the circular features, with brecciation continuing to the end of the drill hole.
-
Athabasca Basin have circular structures associated with brecciation, alteration and uranium mineralization.
-
This showing comprises low sulphidation epithermal style quartz veining and brecciation coinciding with geochemical anomalies in soils and an NSAMT (Natural Source Audio Magnetic Telluric) structural target.
-
-- Drill core recovery may be reduced because of the brecciation and soft unconsolidated material and hence the recovered material may not be representative of the material drilled.
