Shocked quartz is a form of quartz that has a microscopic structure that is different from normal quartz. Under intense pressure (but limited temperature), the crystalline structure of quartz will be deformed along planes inside the crystal. These planes, which show up as lines under a microscope, are called planar deformation features (PDFs), or shock lamellae.

Famous quotes containing the word shocked:
“I went to my father’s at night. He spoke of poor John [Boswell’s brother] with disgust. I was shocked and said, “He’s your son, and God made him.” He answered very harshly, “If my sons are idiots, can I help it?””
—James Boswell (1740–1795)
