These are usually quartz and clay minerals, though collophane (cryptocrystalline apatite, a phosphate mineral) is also sometimes present, as nodules or as small pellets interpreted as fecal pellets.It is shown that the high relative roughness of the interface compared to the chalk grain size results in the ultimate interface shearing angles falling close to the chalk-chalk shearing resistance angles. The δʹ angles also increased by up to 5° over 38 days of ageing. 1 Introduction Chalk is a weak rock, with Unconfined CompressiveChalk is also a source of quicklime by thermal decomposition.

The best way of understanding the effect is to consider the variable admixture of grains of two sizes (Figure 2.4).determined by the grain density-bulk density relation, was 25.0 percent where the bulk volume was obtained by micrometer measure­ ment, but the total porosity was 23.6 percent where the bulk volume was obtained by mercury displacement. These results indicate that mercury displacement determinations of bulk volume tend toward
