Book Description
Excerpt from Foraminifera From the Type Section of the San Lorenzo Formation, Santa Cruz County, California Subsequently, different thicknesses have been reported for the San Lorenzo for mation, most of them (though not all) greater than the original estimate, and both the lower and upper contacts have been more closely observed and sometimes disputed. Schenck (1936, p. 69) stated that the San Lorenzo formation lies with probable disconformity, but without marked angular unconformity, above the Butano sand stone in the Kings Creek area, and recorded a measured thickness of feet for the San Lorenzo formation along the San Lorenzo River in contrast to Arnold's original estimate of about feet. Schenck further stated (p. 72) that on the San Lorenzo River the Vaqueros lies with questionable disconformity above the San Lorenzo formation. A year later, in an abstract discussing the type San Lorenzo formation, Forrest (1937, p. 326) also suggested that there may be a hiatus between the Butano and the superjacent San Lorenzo, even though the beds are structurally accordant, and in 1943 (p. 199) he recorded a thickness of almost feet for the San Lo renzo formation along Bear Creek and Kings Creek.
