Resumen de Scanning electron microscopy of pulverulite in the Silurian Lockport Dolomite near Rocky Ridge, OH
Pulverulite, a soft, porous, and crumbly rock, is present in the Silurian Lockport Dolomite at a quarry near Rocky Ridge, OH. The great majority of the pulverulite forms bedding-perpendicular pipes. The most common characteristic of the pulverulite, as seen using scanning electron microscopy, is a series of rounded to subrounded masses of dolomite 5-20 µm in diameter. The author interprets that the pulverulite resulted from the downward percolation of very acidic groundwater, that resulted from chemical reactions involving tree roots and groundwater.
