Eventually only a hollow lined by residual soils above a breccia chimney marks the site of a former salt extrusion. |
The ironstone is locally represented by hematite matrix-supported vein quartz breccia. |
Some 600 m below this breccia the pluton is pervaded by a fine-grained granophyre, apparently the product of a sudden and final crystallization. |
Intrusive breccias can be the host for metallic ore deposits and aesthetic mineral specimens. |
Massive dolomite and dolomitic breccias are separated by a normal fault from the upper part of the sequence. |
Galena is also found as larger isolated octahedral crystals within the coarse calcite cement in breccias in the upper parts of the core. |
