Abstract

Textural properties of limestones assume a large importance in determining the origin of the rocks. Limestones are usually called detrital rocks if they possess oolitic, pelleted or coquoinoid texture (Pettijohn, 1957, p. 401). This criterion as to whether the rock was formed by current-sorted detritus or direct chemical precipitation is valid if, and only if, the rock texture has remained essentially unchanged during diagenesis. Because many of the Mississippi limestones of Iowa display pellet textures, it is desirable to determine, if possible, the true nature of this texture, and its mode of origin, and whether it reflects a depositional or diagenetic environment.
