“…Oncoids in Ow have irregular random growth which are typically formed in a low-current energy, where the current was not strong enough to create good concentric lamination in the cortices ( Wright, 1983 ) (Figures 16 a and 18 ). Hence, the association of Pg and Ow is a characteristic of a shallow lagoon environment due to the presence of algae, calcimicrobes, and bioclast assemblages ( Tucker and Wright, 1990 ; Flügel, 2004 ; El-Yamani et al., 2018 ).…”

Triassic carbonate rocks of Pha Kan and Doi Long Formations of Lampang Group consist mostly of carbonate successions deposited in the Sukhothai Zone, northern Thailand. These formations are mixed carbonate and siliciclastic sediments and widely exposed in the Lampang area. These deposits are important for the reconstruction of depositional environments and regional correlations of the Triassic carbonate rocks with respect to the volcanic arc of the Sukhothai Zone during the Triassic. The goal of this study is to analyze the lithology and microfacies of the carbonate rocks of the Pha Kan and Doi Long Formations and reevaluate the existing depositional models and carbonate settings. Both formations have diverse skeletal fossils, including foraminifers, sponges, calcimicrobes, calcareous algae, bivalves, echinoderm spines and fragments, ostracods, gastropods, and other fossils. Based on field observations and microfacies analysis, twelve major facies, corresponding to specific depositional environments within a carbonate setting, have been established. The inferred depositional environment is a carbonate platform with a well-developed lagoon, small-scale reefs, and bioclastic and oolitic shoals, as parts of a carbonate ramp. The microfacies and sedimentological study show that this carbonate system was influenced by the nearby volcanic arc. Consequently, our study shows that the Lampang Group in northern Thailand can be correlated with the Lincang Massif of the western Yunnan Province, PRC and the northwestern Lao PDR.

This paper aim to review currently four main approaches to paleoenvironment and paleoclimate research including: 1) paleotonlogy, 2) sedimentology, 3) major and trace element geochemistry, 4) stable isotopes. Sedimentary and geochemical proxies are widely used for many different sedimentary environments and ages. Paleontological proxies have limitation due to the poor preservation of fossil. The use of stable isotopes proxy to study paleo-environment and paleoclimate is new trend that can be applied to wide variety of subjects, from organisms to minerals sensitive to environmental change. The environmental and paleoclimate information obtained from the above four approaches is not the same in terms of information type and level of detail. Paleontology only provides general information on the geographical conditions such as the continental environment, shallow seas, deep seas and continental shelves without detail on the environmental characteristics. Sedimentary records are likely to provide more detail on environmental and geographical information than paleontology proxies. The geochemical proxies provide information related to redox, humid or arid condition, high or less precipitation. Stable isotope provides the most quantitative approach compared to the others. The information obtained from this approach is based primarily on oxygen and carbon isotopes to reconstruct the history of temperature changes in the ocean and atmospheric environment. The quantitative level of the information obtained is gradually increased from the palaeontological, sedimentary, geochemical to stable isotope proxy. There is no unique optimal approach to paleo-environmental and paleo-climate research, therefore, in order to get a detailed and quantifiable information it is required to apply synchronously all four approaches mentioned above.
