At subsequent stages of exploration (5-8) carried out exploration of identified deposits and schlich testing plays a supporting role.
The method of testing schlich river systems.
Methods schlich testing of river systems is largely dependent on cycles of development of the hydrographic network and its degree of maturity. In the upper reaches of river systems is allocated zone of mature valleys of the previous erosion cycle, which is characterized by valley placers. However, with a slight manifestation of lateral erosion and weak erosion of any indigenous sources can be formed only a small leakage fluxes in modern fluvial facies. Several downstream there is a zone of deepening river valley, within which the predominant active bottom erosion. The result is a dissection of indigenous sources of salinity in the sides of valleys or erosion of the old valley placers.

Ore to make a material enters the river channels, they appear clear schlich anomalies, and under favorable conditions - river bed and terrace placers. Another area of ​​expansion is located below the river valleys, dominated by lateral erosion, which are carried out under the influence, change and destruction of the terraces of previous cycles of erosion, erosion of the affected side of the river valleys and the anterior root mineralized zone. In this form schlich anomalies in various types of loose sediments, channel placers are converted in the valley and destroyed the old terraces placers. Downstream areas are mature valleys of the new erosion cycle, which ends with the development of valleys, dominated by the accumulation of clastic material, its change and differentiation.
Take a look at testing of river systems in the initial phases of the erosion cycle.
