The Quartz Crystal Section. The decision to make large scale use of crystal control in military communication systems was made late in 1939. The Armed Services had considered crystal control before but the idea was always rejected on the bases of (1) lack of flexibility, (2) cost, and (3) unavailability.

Fine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it's called shale. Otherwise, it's siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay).

Throughout the grinding wheel's history, the bond that holds the abrasive grains together has proven as important as the grains themselves. The success of grinding wheels began in the early 1840s, when bonds containing rubber or clay were introduced, and by the 1870s a bond with a vitrified or glass-like structure was patented.

Quartz grains take several forms: detrital quartz asperities, euhedral microquartz, quartz nanospheres, quartz overgrowths, and grain replacements. Smectite to illite transformation, dissolution of skeletal fragments (e.g., biogenesis), pore and fracture fillings, and pressure solution are likely sources for authigenic quartz during diagenesis.
