L.S. Waterman Frank T. Manheim F.L. Sayles 1973 <p>The sediments cored on Leg 19 consist primarily of diatomaceous oozes with variable proportions of volcanic material and terrigenous clays and silts. With a few exceptions, deposition rates are high at these sites, usually exceeding 5cm/10³y. The interstitial solutions sampled exhibit compositional changes which previously have been found to characterize rapidly deposited terrigenous sediments. Some of the largest changes in Na⁺, K⁺, Mg²⁺, Cl^-, and HCO³ yet found in DSDP samples occur in the pore waters studied from this leg (see Table 1).</p> application/pdf 10.2973/dsdp.proc.19.133.1973 en National Science Foundation Interstitial water studies on small core samples, leg 19 article
