In this case, the collision is between the Pacific Plate and the North American Plate. In the Mecca Hills in California, the clay gouge has been squeezed up to form a linear ridge. \u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #660000;\"\u003e\u003cstrong\u003eA displacement of strata along with gouge along the line of displacement are marks of faulting. On a smaller scale, gouge is found in most fault zones, though not as a massive ridge. These specimens are clay, so students should handle with care.
