    Magmatic switch-on and switch-off along the South China continental margin since the Permian: Transition from an Andean-type to a Western Pacific-type plate boundary

    Detrital zircon provenance data for the Tananao schist in eastern Taiwan is consistent with its protolith being deposited on the South China continental margin at around, or soon after, 150 Ma, rather than being of an exotic origin and much older as previously suggested. The absence of ca. 200 Ma zircons agrees with the presence of a magmatic gap in the region after the orogenic and magmatic front migrated to central South China, due to a flat-slab subduction. The characteristic lack of input from interior South China (i.e., the lack of 1100–750 Ma and 470–420 Ma populations), and the immature nature of some of the schist units, suggest that they were sourced from the nearby coastal regions. On the other hand, they exhibit a dominant 190–150 Ma magmatic zircon population, suggesting the presence of abundant magmatic rocks of that age along the coastal regions. This, along with our newly discovered ca. 180 Ma I-type granites from eastern Zhejiang and other ca. 190–180 Ma magmatic rocks recently reported from the coastal regions, led us to propose that a new continental arc was initiated after ca. 190 Ma along the coastal region after a magmatic gap due to flat-slab subduction. This newly initiated arc likely persisted until ca. 90 Ma, and is represented by the I-type granitic rocks in eastern Taiwan. Slab roll-back likely caused the arc system to retreat towards the Pacific Ocean after 90 Ma, and ca. 60–17 Ma bimodal magmatism adjacent to the South China Sea signifies continental margin extension in the lead-up to, and during, the opening of the South China Sea. We thus argue that the continental margin of East Asia was transformed from an Andean-type plate margin at 280–90 Ma, to the present-day Western Pacific-type plate margin soon after 90 Ma

    Genus Lineacoelotes Xu, Li & Wang, 2008 Lineacoelotes Xu, Li & Wang, 2008: 4. Type species. Lineacoelotes longicephalus Xu, Li & Wang, 2008, from Sichuan Province. Diagnosis and description. Patellae of male palp (lateral view) with a strong seta that is located on a swollen and convex base. For more detail diagnosis and description, see Xu, Li & Wang, 2008. Comments. Lineacoelotes was originally described for five species: L. bicultratus (Chen, Zhao & Wang, 1991), L. funiushanensis (Hu, Wang & Wang, 1991), L. nitidus (Li & Zhang, 2002), L. longicephalus Xu, Li & Wang, 2008, and L. strenuus Xu, Li & Wang, 2008. Based on these data and the new species described below, the genus is distributed in central (Henan, Hubei), southwestern (Chongqing, Guizhou, Sichuan) China.Published as part of Li, Bing, Zhao, Zhe, Chen, Haifeng, Wu, Zhiyan & Li, Shuqiang, 2019, New species of the coelotine spider genus Lineacoelotes (Araneae: Agelenidae) from China, pp. 351-363 in Zootaxa 4623 (2) on page 352, DOI: 10.11646/zootaxa.4623.2.9, http://zenodo.org/record/325550

    1^{1} G. Moruzzi and Li-Hong Xu, Ohio State University 49th International Symposium on Molecular Spectroscopy, TD04, p. 122 (1994).Author Institution: Università di Pisa, Piazza Torricelli 2, I-56100 Pisa, Italy; National Institute of Standards and Technology, Gaithersburg, MD 20899 U.S.A.Following last year's Columbus talk1talk^{1}, we have continued our work on an interactive computer program for automating assignment of the Fourier-Transform methanol spectrum. Two new features have been developed. (1) A new routine has been incorporated in the Ritz program for the identification of small-amplitude vibrationally excited levels starting from the known energies of the ground-vibrational levels. We have been testing this routine in the 9501250cm1950-1250 cm^{-1} region for CH3OHCH_{3}OH. (2)A new LaseRitz program has been written for predicting FIR laser lines using known energies of the ground and the vibrationally excited levels. The simplified float chart of the interactive program is presented below

    Contractive Matrices of Hua Type

    This is continuation of the recent work by Xu, Xu and Zhang [Revisiting Hua–Marcus–Bellman–Ando inequalities on contractive matrices, Linear Algebra Appl. 430 (2009), pp. 1499–1508] on contractive matrices. We study the relations of block matrices of Hua type, present some properties that the eigenvalues of Hua matrices possess, especially for the 2 × 2 block case, discuss the analogues for higher dimensions and estimate the closeness of two Hua matrices. At the end, we propose a conjecture on the eigenvalues of Hua matrices and an open problem on the symmetric functions of the eigenvalues of contractive matrices
