The Lac au Renard Tephra Cluster: a record of Lochkovian (Lower Devonian) volcanism in the Indian Point Formation, Gaspe Peninsula, Quebec, Canada

Approximately twenty tephra beds, comprising the Lac au Renard Tephra Cluster (new), occur in the Rosebush Cove and Petit Portage members of the Indian Point Formation (Chaleurs Group) on the Gaspe Peninsula of Quebec, Canada. The tephra beds range in thickness from <1.0 cm to 82 cm and occur in a mudrock-dominated sequence with coarser tempestite interbeds. Mineralogically and texturally graded accumulations of phenocrysts mark the bases of the thickest tephra beds. Early diagenetic concretions in one composite tephra preserve pre-compaction fabrics and original hypocrystalline textures with microphenocrysts and devitrified glass shards. The presence of plagioclase, quartz, K-feldspar, biotite, apatite, and zircon suggest a rhyolitic source. The coarseness of the microphenocrysts in the basal accumulations, along with the abundance and thickness of the tephras, suggest that deposition in the Gaspe area was in a proximal position relative to the volcanic source. The zonal graptolites Monograptus praehercynicus and Monograptus aequabilis ssp. from the Petit Portage Member indicate a middle Lochkovian age for the Lac au Renard Tephra Cluster of the Indian Point Formation. Correlation with the tephra cluster that includes the Judds Falls Bentonite in the New Scotland Formation and other possible tephras in the Kalkberg Formation (Helderberg Group) of New York and the Corriganville and Mandata formations of Pennsylvania is likely. The graptolite fauna of the Indian Point and probable correlations to New York may provide additional biostratigraphic constraints on a U–Pb zircon radiometric age determination of 417.6 Ma from New York that has been used to estimate the age of the Silurian–Devonian boundary.

24 Tirtha’s of Ramanatha Swamy Temple, Rameswaram

We know Ramayana and Ramesawaram, the memorable temple located at the tip of Indian Point in Tamil Nadu. It is the most important visit in the Hindu Religion and through the year tourist multitude the place to take a bath in the famous “Tirthams” of Rameswaram. Ramanathaswamy Temple is a Hindu temple enthusiastic to the god Shiva located on Rameswaram island in the state of Tamil Nadu, India. Rameswaram Temple Tirthas are the holy wells situated inside the Rameswaram Temple in Tamilnadu, India. There are sixty-four Tīrthas (holy water bodies) in and around the island of Rameswaram. According to Skanda Purana, 24 Tirthas in Rameswaram are important and taking snan (bathing) in them are considered equivalent to penance. Twenty-TwoThirth as are inside Ramanatha Swami Temple.

New Outlines of Structural Sociology, 1945–70

This chapter presents a discussion of international intellectual trends in the social sciences, theoretical and empirical studies in India, the question of independence of mind or home rule in intellectual institutions. Following the swarajist project outlined earlier of viewing Europe and its systems of knowledge and practices from an independent Indian point of view, this chapter is in effect a research outline for a new structural sociology in India. We are introduced to structuralism as it exists in the world, its scope and definition and as a methodology for the social sciences. This is followed by the approach to structuralism as scientific theory, method and as philosophical world view. Finally discusses are the principles of structural analysis, structuralism in language, literature and culture, in social structure, with regard to society and the individual, religion, philosophy, politics, sociology and social-anthropology.

Boron Injection Tank Repair at Indian Point Unit 3

In the Fall of 2018 Westinghouse designed a welded plug to repair a leak around a previously capped nozzle in the Boron Injection Tank at Indian Point Unit 3. The leak was caused by weld cracking around the nozzle. In order to complete the repair, the existing nozzle and weld needed to be removed by boring into the tank so that a custom plug could be installed. Due to site procedures, welding could not be performed inside the tank, so a single weld on the outside of the tank needed to be designed to meet ASME B&PV Code, Section III requirements. In addition, the tank was manufactured from carbon steel with a stainless steel cladding, so future corrosion of the carbon steel needed to be assessed. The leak was an outage related incident, which required the design to be expedited. This paper will discuss the technical challenges in designing the welded plug to meet the site and code requirements.

The camerate crinoid Scyphocrinites Zenker in the Upper Silurian or Lower Devonian of New Brunswick, Canada

The mid-Paleozoic Scyphocrinites Zenker has a distal attachment modified into a globular flotation structure and, uniquely for a crinoid, joined the obligate plankton. Such a flotation structure has been found in the Indian Point Formation (Pridolian to Lochkovian) of Flatlands, northern New Brunswick. It is most likely Pridolian (Upper Silurian) based on the primitive morphology. This identification is confirmed by the globular gross morphology, multi-plated calcite structure, age and similarity to coeval fossils from Cornwall, southwestern England.
