摘　　要：五莲山-九仙山地质公园,包括2个园区组成,是一个多种地质遗迹资源并存、综合性的中型地质公园。园区内既有代表性的地质构造剖面、独特的地质地貌景观,又有地质灾害遗迹。查明九仙山园区西部保存了7亿年前地壳形成过程中岩浆侵入形成的侵入岩,经历了三叠纪华北板块与扬子板块碰撞而发生强烈的变质变形,属于新元古代荣成岩套,锆石SHRIMP U-Pb测年结果,其形成年龄799Ma,变质年龄255Ma;九仙山中东部和五莲山主要为中生代早白垩世崂山超单元晶洞二长花岗岩,形成年龄120Ma。Wulianshan-Jiuxianshan geopark includes two parks. It is a comprehensive medium geoparkthe with a variety of geological heritage resources. There are not only representative geological structural sections and unique geological landscapes, but also geological disaster relics. It is identified that intrusive rocks formed by magma intrusion in the crust formation process existed in west of Jiuxianshan park in 700 million years ago. It has experienced intense metamorphism and deformation formed by the collision of Triassic North China plate and Yangtze plate, and belongs to the Neoproterozoic Rongcheng rock series. According to zircon SHRIMP U - Pb dating results, the formation age is 799Ma, and metamorphic age is 255Ma. Middle and eastern part of Jiuxianshan and Wulianshan are adamellite of miarolitic cavity in Laoshan superunit in Mesozoic early Cretaceous period. Its forming age is 120Ma.
