The garnet-district of Bohemia is situated about 60 kilometers northwest of Prague, and is bounded on the north by Meronitz and Trebnice, 12 miles apart, and by Decany and Skan on the south. This region is covered with alluvium resting on the diluvium, which is undoubtedly equivalent to our glacial drift, and in turn rests on the Cretaceous Pläner-kalk formation. All these strata have been penetrated in places by basaltic and phonolitic outflows. A tract of 70 square kilometers constitutes what is known as the garnet-district of Bohemia. It is probable that garnets may be found within a larger area, but only in a space of 7 square kilometers are they abundant. They are found loose in the soil or in the lower part of the diluvium, or are embedded in a serpentine rock.
