“…The thickest and most deformed formation exposed within the KKFTB is the Khao Khad Formation, which tectonically underlies the Sap Bon Formation and is thrust over the Nong Pong Formation to the north. In the Saraburi area of the KKFTB, the Khao Khad Formation consists of approximately 1400 m of tectonically thickened Permian carbonate platform facies [ Dawson et al , ; Morley et al , ; Warren et al , ; Arboit et al , ] (Figure ). The present trend of the belt (from E‐W to ENE‐WSW) lies at a high angle to the interpreted orientation of the approximately N‐S Indosinian suture zones that run throughout SE Asia.…”

“…Fracture populations in the field have been sampled along Highway 21 (Figure b), along a N‐S oriented section within the KKFTB where the Khao Khad Formation crops out. The Permian carbonate of the Khao Khad Formation contains a great variety of fractures, many filled with calcite, which developed during the Indosinian Orogeny [ Warren et al , ]. The term fractures is here used in a general sense to refer to either (Type I) opening‐ (Types II and III), sliding‐, or closing‐mode displacement discontinuities along surfaces, such as planar surfaces, pressure‐solution seams, joints, and veins [ Pollard and Aydin , ].…”

In polyphase tectonic zones, integrating a study of fault and fracture with calcite twin analysis can determine the evolving paleostress magnitudes and principle stress directions that affected the area. This paper presents the results of the analyses of fractures, striated faults, and calcite twins collected within the Khao Khwang Fold-Thrust Belt in central Thailand (SE Asia). Here we attempt to reconstruct the orientation of the principal stresses that developed during the tectonic evolution of this highly deformed, polyphase orogen. Tectonic data were collected in the Permian carbonates of the Khao Khad Formation of the Saraburi Group, and five successive tectonic stages are determined that are interpreted to have developed before, during, and after, the Triassic Indosinian Orogeny. The first three stages predate the main deformation event: the first stage is interpreted as a pre-Indosinian N-S extensional stage, the second stage described a N-S strike-slip and compressional regime, largely perpendicular to the fold axes of the main structures, while the third stage is associated with an E-W compressional strike-slip phase. A further two stages took place after, or during, the main folding event and correspond to N-S compression and to an E-W composite strike-slip/contractional stage, the latter which is interpreted to represent Cenozoic deformation related to the India-Asia collision.

“…The δ 18 O values from carbon and oxygen stable isotopes analysis were used as a proxy for the relative temperature at which syntectonic calcite mineralization occurred along the five sample faults in shale quarry S (i.e., Warren et al, 2014;Hansberry et al, 2015). Three samples were taken from each fault sampled for K-Ar dating of illite, with δ 18 O VPDB values ranging from −13.51‰ to −9.01‰, while δ 13 C VPDB values range from 4.93‰ to 1.20‰.…”

“…An understanding of fluid-rock matrix interaction history can be useful to constrain the development of a fold-thrust belt (Wiltschko et al, 2009;Lacroix et al, 2014). Carbon and oxygen stable isotope data have been used to investigate the relative temperatures at which carbonates and vein cements precipitated, and to characterize the stage of burial, diagenesis, and/or orogenesis recorded (Lacroix et al, 2014;Warren et al, 2014;Hansberry et al, 2015). Recent work in the Saraburi Province (Warren et al, 2014), and in the Sap Bon Formation in particular, has defined a fluid-rock matrix interaction history and model of the structural and fluid-flow evolution of the upper level detachment zone (Hansberry et al, 2015).…”

K-Ar dating of illite in fault gouges is a useful tool for constraining the timing of brittle fault movement; however, this can be problematic in fault gouges hosted in clay-rich rocks due to the influence of host-rock material. Therefore, this study employs a multianalytical geochemical approach to unravel the influence of host-rock mineralogy, as well as fault zone development, on ages from fault-gouge samples in a shale detachment zone. K-Ar dating of the ≥2 µm fraction of 6 samples from the Sap Bon Formation detachment zone and associated fault zones in the Khao Khwang fold-thrust belt of central Thailand yielded an age range of 262 ± 5.4 to 208 ± 4.6 Ma. Carbon and oxygen stable isotope analysis along with X-ray diffraction mineralogy indicate that the samples with the youngest K-Ar ages are characterized by higher grade clay mineralogy, and hotter, orogenic fluid temperatures. Using these proxies and comparison to existing geochronology of the study area, we correlated K-Ar illite ages to one of three stages of fault zone evolution: detrital, diagenetic (burial), and authigenic (fault movement). The youngest K-Ar dates in the Sap Bon Formation are contemporaneous with recently published zircon province data indicating that faulting and detachment zone formation in the Sap Bon Formation were occurring by the mid-Late Triassic, with deformation continuing as late as the Rhaetian.
