| Lovering, Tweto, and Lovering noted small veinlets of tetrahedrite cutting interbanded chalcopyrite and bornite. |
|
| The highly fractured felsite is cemented by veinlets of chrysocolla and malachite with minor amounts of cuprite. |
|
| The ore zone is a combination of veinlets, lenses, and nests of pyrite and quartz. |
|
| Some of the material contained micaceous masses of specular hematite associated with quartz, epidote, and numerous veinlets of calcite. |
|
| It mainly occurs as coatings on walls of cavities and as veinlets in fractures. |
|
| These lode deposits occur as a strata-bound series of thin veins and veinlets that carry free coarse-grained and high-grade gold. |
|
| An exception may be its type locality in Colombia, where it occurs in veinlets and pockets in carbonaceous sedimentary units apparently distant from igneous rocks. |
|
| The first several sporophyte fronds were simple, cuneate at base, with single or forked free veinlets. |
|
| Over this interval, disseminated and veinlets of copper oxide mineralization occur in brecciated and sheared coarse grained dolomite. |
|
| The gold is associated with pyrite, pyrrhotite, quartz in veinlets, amphiboles and garnets. |
|
| This mineralization takes place as breccia matrix fill, disseminations and veinlets in altered andesites. |
|
| Weak to moderate quartz and quartz-ankerite veinlets were observed in the drill holes along with locally weak to moderate argillic alteration. |
|
| It differs from the new species described below also in an incurved postmedial band, which is rectangularly indented at radial veinlets. |
|
| Silicification is present in the form of vuggy silica, chalcedony banding and quartz veinlets. |
|
| Molybdenum and copper mineralization occurs in these intrusions in veinlets and as disseminations with coarse molybdenite and chalcopyrite. |
|
| Acanthite and stromeyerite occur as veinlets, stringers and lenses in the High Grade and No 3 vein, giving rise to bonanza style grades. |
|
| In the latter areas, ore-related veinlets clearly cut an earlier barren silicification that exploited pathways generated by fracturing of the rocks along perlitic cracks. |
|
| The intensity of mineralization generally decreases below 500m and comprises quartz-limonite veinlets, azurite, malachite, cuprite, and minor chrysocolla. |
|
| Gold values are associated with quartz vein and veinlets which occur along a steeply dipping horizon of interflow sediments with minor felsite dykes. |
|
| Strong mineralization consisting of quartz-pyrite veinlets developed along intense foliation of carbonaceous slates has been intercepted in the first four holes. |
