Form of Deposit or Seam Coal seams in Australia are generally found as tabular deposits which extend over large areas, usually at low dip angles ( fairly flat, not steeply inclined). Seam thicknesses vary, but usually on a gradual basis except where local quot;washoutsquot; occur, where a portion of seam has been eroded away and refilled with stone deposits in the distant past.
