The results indicated that the mineralization of the original SOC was accelerated by maize root exudations more significantly in low N application rate than in high N application rate, which was probably due to more N demands from soil organic matter in the case of low N application rate.

由此说明，在养分不足的条件下，玉米根分泌物可能更能激发土壤原有机质的矿化，从土壤中获得更多的养分。

运用原子力显微镜，证明了地气携带钠米颗粒向上运移，可能在地表土壤中积累形成地球化学异常的部分增量，为化探找矿和构造研究提供了依据。

The primary provenance of gold placers are various gold deposits and gold mineralization zones of pre-Mesozic Era.

砂金矿的主要原生物源是前中生代各类金矿床和金矿化体，它们多已风化、剥蚀殆尽，而中生代晚期岩金矿体得以保存

For metallogenic environments, the neotectonic movement and climate are 2 most important factors. The neotectonic movement controlled the exposure, weathering and migration of primary provenance, the formation of valleys, the evolution of river systems and topography, and etc. The climate factor played important roles in the whole history of gold placers, especially in the formation of secondary provenance, the sorting and concentration of placer gold, the conservation and regeneration of gold placers, and etc.

在成矿环境方面，新构造运动对砂金矿的形成演化具有重要控制作用，主要表现在促使原生源暴露地表、风化、迁移，控制河谷的发育、水系与地貌的变迁等；气候因素贯穿于砂金成矿全过程，尤其在次生物源的形成、砂金的分选、富集、保存、&再生&等方面发挥重要作用。

The main primary provenance of placer gold are rock gold deposits. The tributary gold placers and weathering crust of free gold-bearing are prime secondary sources.
