This research highlights the importance to study the magmatic plumbing systems in Southern Puna, NW Argentina, emphasizing the significance of understanding the genesis of sub-volcanic bodies and their implications for the crustal assimilation and recycling processes. In the southeastern edge of Ratones salar, Southern Puna, there is an intrusive body cropping out, named Soroche Porphyry. This intrusion is formed by porphyritic rhyodacitic, basaltic andesites, and porphyritic andesitic rocks, with magma mixing relations between the mentioned lithologies. The main features of the Soroche Porphyry are described to interpret the dynamic aspects of magma mixing, identify and define textural, mineralogical, and geochemical features, directly related to the mentioned process. Taking into account these features, the results showed that a hybrid magma (homogeneous porphyritic andesite) was produced by mixing processes between basaltic andesitic and rhyodacitic magmas, whereas, the heterogeneous porphyritic andesite represent mingling areas, whereby the end members are easily identified. Furthermore, we dated the main rocks of the porphyry using zircon U–Pb methodology by LA-MC-ICP-MS, complemented by Hf isotopes analyses. The geochronological data evidenced magmatic activity around ~15 Ma, allowing the correlation of the Soroche Porphyry with the Inca Viejo Formation. The basaltic andesites yielded a zircon U–Pb age of 15.63 ± 0.08 Ma, the heterogeneous porphyritic andesites displayed an age of 15.52 ± 0.16 Ma, and the rhyodacites showed an age of 15.13 ± 0.12 Ma. The isotopic Ɛ_{Hf (15 Ma)} values from the rhyodacite between −4.9 and −11.3, suggested a great amount of crustal components, evidencing that the rhyodacitic magmas derived from assimilating and recycling crustal rocks probably from the lower Paleozoic rocks.

这项研究强调了研究阿根廷西北部南部普纳市岩浆管道系统的重要性，强调了了解次火山体成因的重要性及其对地壳同化和再循环过程的影响。在南普纳（Raunas salar）南部东南部的拉通斯撒拉（Ratones salar）边缘，出现了一个侵入体，名为Soroche Porphyry。这种侵入是由斑状的流纹岩，玄武质的安山岩和斑状的安山岩构成的，在上述岩性之间具有岩浆混合关系。描述了Soroche斑岩的主要特征，以解释岩浆混合的动态方面，识别和定义与上述过程直接相关的质地，矿物学和地球化学特征。考虑到这些功能，结果表明，通过玄武质安山岩和流纹岩安山岩之间的混合过程产生了杂岩质（斑岩安山岩），而杂质斑岩安山岩代表了混合区域，从而易于识别端部成员。此外，我们通过锆石U–Pb方法（通过LA-MC-ICP-MS）对斑岩的主要岩石进行了测年，并进行了Hf同位素分析。地质年代学资料证实了约15 Ma左右的岩浆活动，这使得Soroche斑岩与印加维耶霍地层具有相关性。玄武质安山岩的锆石U–Pb年龄为15.63±0.08 Ma，异质斑状安山岩的年龄为15.52±0.16 Ma，而菱锰矿的年龄为15.13±0.12 Ma。同位素Ɛ 异质斑岩安山岩代表混合区域，因此易于识别端部成员。此外，我们通过LA-MC-ICP-MS用锆石U–Pb方法对斑岩的主要岩石进行了测年，并进行了Hf同位素分析。地质年代学资料证实了约15 Ma左右的岩浆活动，这使得Soroche斑岩与印加维耶霍地层具有相关性。玄武质安山岩的锆石U–Pb年龄为15.63±0.08 Ma，异质斑状安山岩的年龄为15.52±0.16 Ma，而菱锰矿的年龄为15.13±0.12 Ma。同位素Ɛ 异质斑岩安山岩代表混合区域，因此易于识别端部成员。此外，我们通过LA-MC-ICP-MS用锆石U–Pb方法对斑岩的主要岩石进行了测年，并进行了Hf同位素分析。地质年代学资料证实了约15 Ma左右的岩浆活动，这使得Soroche斑岩与印加维耶霍地层具有相关性。玄武质安山岩的锆石U-Pb年龄为15.63±0.08 Ma，非均质斑状安山岩的年龄为15.52±0.16 Ma，而菱锰矿的年龄为15.13±0.12 Ma。同位素Ɛ 地质年代学资料证实了大约15 Ma左右的岩浆活动，这使得索罗什斑岩与印加维耶霍地层具有相关性。玄武质安山岩的锆石U–Pb年龄为15.63±0.08 Ma，异质斑状安山岩的年龄为15.52±0.16 Ma，而菱锰矿的年龄为15.13±0.12 Ma。同位素Ɛ 地质年代学资料证实了约15 Ma左右的岩浆活动，这使得Soroche斑岩与印加维耶霍地层具有相关性。玄武质安山岩的锆石U–Pb年龄为15.63±0.08 Ma，异质斑状安山岩的年龄为15.52±0.16 Ma，而菱锰矿的年龄为15.13±0.12 Ma。同位素Ɛ流纹岩的_{Hf（15 Ma）}值介于-4.9和-11.3之间，表明存在大量的地壳成分，这表明流纹岩浆岩浆来自同化和再循环地壳岩石，可能来自下古生界岩石。
