About connection of hydrogeological conditions with thermal anomaly in Matsesta area

Abstract

The Matsesta area is confined to the Sochi artesian basin with the main aquifers belonging to the Cretaceous and Upper Jurassic limestones. The feeding areas of the artesian basin belong to the open anticlinal structures and the northern limestone-filled sides of the basin. The inner feeding areas are located much lower than the marginal ones and are at the same time places of discharge of deep waters of the basin. The thermal springs of Matsesta and Agura are confined to such areas. The thermal regime of the basin depends on cold waters flowing from the feeding areas and thermal waters entering the discharge areas. The therapeutic waters of Stara Matsesta come to the springs through the chalk rocks from different depths and, consequently, have different temperatures.
