One of the key must lie in the area where rocks with different mineral assemblage are found adjacent to each other. Most of the Nagatoro area is categorized as the lowest metamorphic grade zone which is defined by the mineral assemblage without garnet. Several outcrops in this area are known to contain garnet. It has been argued that the appearance of garnet indicates juxtaposition of rocks from different metamorphic grade, suggesting structural discontinuity. To investigate whether the local garnet occurrence was the discontinuity, Raman microspectrometry was applied carbonaceous materials in 27 rock samples in a continuous outcrop in this study. The estimated temperature was 400 to 460℃ with no structural gap or tendency recognizable when mapped. Samples with and without garnet both produced results comparable to each other. No evidence was obtained to show that the local garnet occurrence at the outcrop is due to structural discontinuity. The estimated temperature range was consistent with the beginning condition of the garnet formation. It is likely that the boundary between the garnet bearing rocks and those without garnet was originally continuous, with the condition just on the border to start growing garnet., application/pdf}, pages = {55--60}, title = {Estimated peak metamorphic temperature of the Sanbagawa schists from Nagatoro area, Kanto Mountains, using Raman microspectrometry on carbonaceous materials}, volume = {11}, year = {2017}, yomi = {イヌイ, ムツコ and イズミ, リオ and ワタナベ, タイガ} }
