| 摘 要： | 本文就华北地台南缘豫西洛宁－嵩县地区中生代钙碱性花岗岩基和小斑岩体的同源性，从成岩时代，成岩环境，岩石学，岩石化学，微量元素尤其是稀土元素以及岩石成因类型等８个方面进行了论证，上述花岗岩基与小斑岩体被认为是太古界太华群重熔产物，属于同一重熔－演化系新认识。

| Abstract: | From eight aspects, i. e. rock-forming epoch, rock-forming environment, petro-logy, petrochemistry, trace elements(especially REE)and genetic types of rocks,the authors make a positive discussion on the affinity of Mesozoic calc-alkalinegranite batholiths and small porphry bodies in the Luoning-Songxian area, west-ern Henan Province. A new idea ie proposed that both granite batholiths and smallporphyry bodies are believed to be products of anatexis of the Archean TaihuaGroup and belong to the same remelting evolution series. |
