Abstract
Geological and hydrogeological characteristics of the Lozovy ridge (Southern Primorye) are studied, as far as karst phenomena are widely distributed within its boundaries. Water-bearing rocks of the karst water source “Silver Spring” (“Serebryany Klyuch”), which is located near the bottom of the “Bear’s fang” (“Medvezhiy klyk”) cave, are investigated. It is found that karst rocks are presented by calcite (CaCO3), and an accessory mineral is barite (BaSO4). It is determined that among the trace elements forming the composition of carbonate water-bearing rocks the maximum concentrations are typical for Sr, Ba, Fe, Al, Za, Mn, Cu, and Ni. Also, the chemical composition of the waters taken from the “Silver Spring” water source is studied. These waters are fresh, hydrocarbonate, calcium, and weakly alkaline. Among the elements of the spring, such elements as Sr, Ba, Fe, Al, Zn, Mn, Cu, and Ni have the maximum concentration. The other elements have concentrations less than 1 µg/l.
Highlights
The analysis of the obtained material allows confirming the fact that the carbonate karst type is typical for the Lozovy ridge, where karsting rocks are the limestones of the Chandalazsky suite
Ground waters held in Paleozoic terrigenous-carbonate sediments form the complexes of a fracture-karst-stratal type
The spring waters are characterized by the maximum concentrations of such elements as Sr, Ba, Fe, Al, Zn, Mn, Cu, and Ni, the sources of which are carbonate adjacent rocks
Summary
Limestone karst forms karst areas in the Pyrenees, the Alps, and the Carpathians. The Alps are characterized by intensively developed karst within mountain ice highlands bordered with limestone. In the Carpathians carbonate karst develops, mostly, in reef limestones. In the Crimea karst phenomena are spread in mountain and steppe areas. Karst is rather wide spread in the Urals, Southern Siberia, in spots of Central and Eastern Siberia, and in the Far East. In Eastern Primorye karstland the carbonPermian and high-Triassic rocks are carstified, as well as reef limestones. Sodded and bare karst is distributed with swallow holes, craters, rock shelters, and caves. Sodded and bare karst is spread with swallow holes, craters, sink holes, and pepino hills [3].
