hydrothermal manganese-rich crusts Toth 1980 The Si/Al ratio in the studied manganese ore ranges between 190 and 390 suggesting that Si and Al were derived mainly from detrital-diagenetic components Figure 4 The element Ti is essentially immobile in hydrothermal solutions and has long been recognized...

Evidences Towards Hydrothermal Origin of Manganese

Manganese deposits of Balaghat belt of Madhya Pradesh India occur as shear parallel quartz-manganese interlayers restricted within the mylonite zones of the area The interlayered ore bodies along with the shear planes maintain a co-axial non-coplanar relationship to the S1 schistosity of the country rock They also exhibit folding along S2 and S3 axial trends and attain a sinuous map...
