The paper presents studies on the facies complex of salt rocks of the boron-potassium deposit of the Inder uplift. Among them, the main widespread varieties of rocks are distinguished, namely, sylvine-polyhalite and carn. allite-kieserite. The chemical and mineralogical compositions of these rocks both along the strike of the layers and especially in the vertical section vary within wide limits, but at the same time there are certain patterns of relationships between the composition of minerals. The chemical and mineralogical characteristics of salt rocks are presented for wells where a change in the composition of salt rocks occurs with a transition to essentially carnallite rocks with bischofite. The internal salt tectonics of the deposit is distinguished by exceptional consistency of the general direction of the strike of both the entire structure as a whole, and the features that compose it. This is due to the proximity of the location of the monoclinal structure under consideration to the marginal part of the salt-dome uplift, as well as the basal anhydrite of the upper cycle of salt accumulation. The anhydrite horizons, which are found in the cores of all salt domes, are accepted as markers. The barium to strontium ratio was used to correlate the anhydrites. Based on the distribution of barium and strontium, the main anhydrite horizon was identified, which is of primary importance in establishing the identity of the sections of salt deposits in the domes. The total thickness of the entire salt rock complex exposed in the area is estimated at 750-800 m. The footwall of the boron-potassium deposit contains stratigraphic younger rocks, while the hanging wall contains older ones. The productive strata are characterized by a complex mineral composition and are composed of sylvinites, polyhalite, kieserite, carnallite, and bischofite rocks. In many cases, potassium salts have mixed compositions. The most common boron minerals are hydroboracite, caliborite, preobrazhenskite, boracite, etc.
