Abstract

In the vicinity of Seefeld, in the Austrian Tyrol at an altitude of 1,000 meters lies a rock formation known geologically as Seefeld shale. It is found in veins varying in thick ness from 20 cm. to 100 cm. Enveloping this shale is the Gall enstein formation containing many fossil gastropods. The occurrence of this particular mollusk in large quantities dates the formation as Silurian. The Seefeld formation is a specific bituminous shale which yields a crude oil from which Ichtyhol is made. Centuries ago, the Tyrolian peasants would collect this shale, boil it with water in large pots, and skim off the black tar which came to the top. To this tar was attributed miraculous healing power, and as a curative agent it gained wide fame and usage throughout adjoining districts.
