“…Void-filling phillipsite cements have also been described by Morgenstein (1967), Garrison et al (1973), Bernoulli, Garrison, and McKenzie (1978), and Bernoulli, Garrison, and Mélières (1978). Likewise, in one of these cases oxygen-isotope data suggest a low-temperature origin (Bernoulli, Garrison, and McKenzie, 1978).…”

Deep sea drilling on four seamounts in the Emperor Seamount chain revealed that Paleogene shallow-water carbonate sediments of the "bryozoan-algal" facies crown the basalt edifices. According to the biofacies model of Schlanger and Konishi (1966, 1975), this bryozoan-algal assemblage suggests that the seamounts formed in cooler, more northerly waters than those presently occupied by the island of Hawaii; i.e., the paleolatitudes of formation were greater than 20 °N. Moving southward toward the youngest member of the seamount chain, a facies gradient indicative of warmer waters was observed. This gradient is interpreted as a reflection of a northward shift in isotherms during the time span in which the seamounts were progressively formed (Savin et al., 1975). On all seamounts, sedimentation at the drilling sites occurred in a high-energy environment with water depths of approximately 20 meters. Early-stage carbonate diagenesis began in the phreatic zone in the presence of meteoric water, but proceeded after subsidence of the seamounts into intermediate sea waters, where the bulk, stable isotopic composition was determined. The subsidence into intermediate waters was rapid, and permitted establishment of an isotopic equilibrium which, like the facies gradient, reflects the northward shift in isotherms during the Paleogene. Calcite and zeolite cements comprise the later-stage diagenesis, and originated from solutions arising from the hydrolysis of the underlying basalt.In conclusion, the results of this study of the shallow-water carbonate sediments are not inconsistent with a paleolatitude of formation for Suiko Seamount (Site 433) of 26.9 ±3.5 °N, as determined by paleomagnetic measurements (Kono, this volume).

“…Such phenomena of alteration of volcanic sand and induration by authigenic processes in shallow sea water containing calcareous organisms are not unknown. Indurated sedimentary layers have been described by Morgenstein (1967) and by Hoffert et al (1978), with reference to the same conditions, in shallow warm water.…”

“…These zeolite-rich samples (Fig. 2c), termed as 'zeolitites' (Iyer and Sudhakar, 1993a), are similar to phillipsite slabs (Menard, 1960) and harmotome-rich scorias of the Society Ridge (Morgenstein, 1967), both from the Pacific Ocean.…”

“…The prominent XRD peaks (d=0.315 nm) resemble harmotome (cf. Morgenstein, 1967) and the "Indian Ocean phillipsite" (d= 0.317 nm; area 23"16'S /75"59'E) of Gottardi and Galli (1985). Such zeolitic material also occurs just below the basaltic glass and form substrate for FeMn oxides (Fig.…”

The Central Indian Basin (CIB, 10°–19°S) encompasses morphotectonic features such as seamounts, abyssal hills, faults, fracture zones and lineations and basic to silicic volcanics that were derived from different sources. Instances of incipient hydrothermal event (s) occurred as evident from: (1) spilites that probably formed due to low‐temperature hydrothermal action on the precursory basalts, (2) slabs and fragments of zeolitites which are the consequent products of palagonitization of the basaltic glasses, (3) chemical variations in the ferromanganese crusts, and (4) abundance of volcanogenic‐hydrothermal material (vhm) that includes ochrous sediments and magnetite spherules. The vhm suggests its origin by interaction of Fe‐rich hydrothermal solutions with surrounding sediments. The CIB spherules occur in sediments of ∼10 ka and ∼425 to 650 ka age and are orders of magnitude younger than the 50 to 60 Ma age of the basin. Incidentally, to the north of the basin at ODP Site 717–719 (1°S/81°E) hydrothermal precipitates of inorganic calcite and deposition of sulphide minerals (∼7.5 to 9 Ma and 0.5 Ma) occur as a result of the on‐going intraplate deformation. This paper reviews the above evidences that possibly indicate episodes of localized hydrothermal events in the CIB.
