During the research character of the influence of enrichment (sieving of silty fraction) on reduction of cement and water demand, as well as on the increase od the quality factor of wastes of wet magnetic separation as a component of composite binder was revealed, that is explained by the decrease in concentration of biotite
in the total mass.
25 km east of the Prince of Wales target, a significant zone of sulphide bearing biotite
hornfels within Knob Hill Formation sediments was intersected adjacent to an intensely propylitic altered diorite in drillhole 10CM06, yielding 0.

V supplementation as an alternative substance to antibiotics in growing pigs.
39]Ar method also provides insight into the cooling ages of biotite
and hornblende and the uplift history of the rocks in which they are contained, but space limitations prevent further discussion.

K-Ar dating of biotite

The content of biotite
in the Kinnekulle Bentonite decreases upwards and correspondingly the sanidine content rises.
However loosely, the basement is grouped into three major groups lithostratigraphically viz: the Migmatite-Gneiss Quartzite Complex: comprising biotite
hornblende gneisses, quartzites and quartz schist.

This middle Eocene cooling age is confirmed by hornblende and biotite

The major lithostratigraphic units in the study area include garnet bearing charnockitic, garnet rich and sillimanite rich metapellataic geneisses (khondalitic) and garnet biotite
