This text presents sedimentologic studies through statistical analysis, in 28 sandstones samples from the Botucatu and Piramboia Formations. The area is located nearby Santa Rita do Passa Quatro, in the Northeast part af the Sao Paulo State. The data obtained showed diferent statistical values for the geologic formations, being the sorting coefficient and kurtosis different, but the skewness similar. A sediment classification (SHEPPARD) was carried out with the particle size distribution. The size distribution gnaphic (Sedimentograma) allowed to study the sediments behaviours during transport and deposition.
