Recently decameter Type IV bursts were observed with the radio telescope UTR-2. One of the prominent properties of decameter Type IV bursts is the existence of fine structure in the form of bursts in emission and absorption. These bursts have practically the same frequency drift rates and durations at decameter wavelengths as the standard Type III bursts, but there are a lot of cases, when the drift rates have an opposite (positive) sign of drift rates. The results of the statistical analysis of bursts in emission and absorption and a comparison of their properties with those of usual Type III bursts are presented in the report. The functional dependences of drift rates and durations via frequency are derived. The connection of properties of these bursts with the position of active regions on the solar disk is discussed.
