“…Some measured temperatures in mid-hole (Iijima and Utada, 1971) fall below the linear extrapolation, which suggests that the measurements at lower temperatures do not represent those of the rock, which should form a series in a slightly convex upward curve. Whatever the inaccuracies of the linear extrapolation method, they are presumably the same in all of the wells, and, thus, the temperatures used will be internally consistent and useful for comparison between the wells.…”

“…Previous studies (Iijima and Utada, 1971;Iijima, 1986) of samples from the MITI deep drill holes in Japan have shown that the zeolite facies boundaries were essentially temperature dependent. The temperature range of the alkali zeolite-analcime boundary (zones II/III) was determined to be between 80 ~ and 95~ b~sed on bottom-hole temperatures.…”

Abstract--Clay and zeolite mineral assemblages were determined for five deep wells in volcano-clastic sediments (Japan) and for one well in mudstones (California). The clay mineral suites in these wells showed a gradual change with depth of illite/smectite (I/S) composition, which increases in smectite content in the upper portion towards a fully expandable mineral (2-3-km depth) and then decreases in smectite content with depth (2-5 km). The temperature of transformation or recrystallization to a fully expandable smectite mineral is about 60~176 in non-zeolite bearing rocks and 70~176 in zeolitebearing rocks, with no apparent dependence on time. Comparison is made between the I/S smectite content in the lower part of the wells (i.e., below the occurrence of the fully expandable mineral) and the zeolite mineral zone boundaries. The 60% smectite composition was found at 108~176 maximum burial temperatures. The zeolite II/III zone boundary, i.e., the onset of the analcime zone, occurs between 85 ~ and 95~ and may be slightly time-related in the span of 1-15 Ma. The clay and zeolite minerals can be used as temperature indicators in the range of the Neogene age.

“…In addition, Hillier (1993) showed that corrensite occurs at 120-260~ in Devonian lacustrine mudrocks. Iijima and Utada (1971) reported that the formation of corrensite at the expense of trioctahedral smectite was observed at a depth equivalent to 85-95~ which was assigned to the analcime zone. This temperature of first appearance of corrensite was used as a paleothermometer in subsequent studies (Hoffman and Hower, 1979;Pollastro, 1993).…”

Abstract--Clay mineral diagenesis in the Niigata basin is documented by mineralogical and chemical analysis of clay minerals from cuttings from the Shinkumoide SK-1D (SSK-1D) well which is characterized by alternating beds containing dioctahedral and trioctahedral smectite minerals with increasing depth. Dioctahedral smectite shows a progressive increase in illite interstratification with increasing depth. The transition of dioctahedral smectite to interstratified illite-smectite (I-S) is supported chemically by an increase in K and A1 and a decrease in Si with increasing depth. In contrast, trioctahedral smectite (saponite) reacts to form a 1:1 interstratified chlorite-smectite (C-S) with increasing burial depth and temperature. Considering the geology and the occurrence of smectite, the SSK-1D smectites probably altered diagenetically from two different parent materials: dioctahedral smectite is derived from clastic sediments and transforms to interstratified illite-smectite, whereas trioctahedral smectite is derived from andesitic pyroclastic rocks and transforms to interstratified chlorite-smectite.The C-S occurs at the same depth of --3200 m as the conversion of randomly interstratified (R = 0) I-S to (R = 1) I-S. Furthermore, the depth is compatible with a T~,~ temperature of 430-435~ which indicates the starting temperature for oil generation from organic matter. The temperature of the conversion of (R = 0) I-S to (R = 1) I-S and the start of corrensite formation is estimated at 110-120~ based on the time-temperature model suggested by others. The clay-mineral diagenesis in the SSK-1D further suggests that I-S and C-S can act as geothermometers in clastic and pyroclastic sediments provided that the effect of time is considered.

Many chloritic minerals in low-grade metamorphic or hydrothermally altered mafic rocks exhibit abnormal optical properties, expand slightly upon glycolation ("expandable chlorite") and/or have excess A1 w relative to A1TM, as well as significant Ca, K and Na contents. Chloritic minerals with these properties fill vesicles and interstitial void space in low-grade metabasalt from northern Taiwan and have been studied with a combination of TEM/AEM, EMPA, XRD, and optical microscopy. The chloritic minerals include corrensite, which is an ordered 1:1 mixed-layer chlorite/smectite, and "expandable chlorite", which is shown to be a mixed-layer chlorite/corrensite. Corrensite and some mixed-layer chlorite/corrensite occur as rims of vesicles and other cavities, while later-formed mixed-layer chlorite/corrensite occupies the vesicle cores. The TEM observations show that the mixed-layer chlorite/corrensite has ca. 20%, and the corrensite has ca. 50% expandable smectite-like layers, consistent with XRD observations and with their abnormal optical properties. The AEM analyses show that high Si and Ca contents, high AlVl/A1TM and low FeVl/(Fe+ Mg) vl ratios of "chlorites" are correlated with interstratification of corrensite (or smectite-like) layers in chlorite. The AEM analyses obtained from 200-500 A. thick packets of nearly pure corrensite or chlorite layers always show that corrensite has low AlIV/SiIV and low FeVI/(Fe + Mg) vI, while chlorite has high AlIV/Si~V and high FeW/(Fe + Mg) vl. This implies that the trioctahedral smectite-like component of corrensite has significantly lower AlIV/Si TM and FeVl/(Fe + Mg) w. The ratios of FeVI/(Fe + Mg) vt and AllV/Si TM thus decrease in the order chlorite, corrensite, smectite. The proportions of corrensite (or smectite-like) layers relative to chlorite layers in low-grade rocks are inferred to be controlled principally by Fe/Mg ratio in the fluid or the bulk rock and by temperature. Compositional variations of" chlorites" in low-grade rocks, which appear to correlate with temperature or metamorphic grade, more likely reflect variable proportions of mixed-Offprint requests to: Yen-Hong Shau layered components. The assemblages of trioctahedral phyllosilicates tend to occur as intergrown discrete phases, such as chlorite-corrensite, corrensite-smectite, or chlorite-corrensite-smectite. A model for the corrensite crystal structure suggests that corrensite should be treated as a unique phase rather than as a 1:1 ordered mixed-layer chlorite/smectite.
