adj.
地面上的，地面上发生的；接近地面的。
Examples
- Subaerial erosion occurs often with reduction to a peneplain .
陆上侵蚀常夷平成准平原。 - The - ray spectrometric survey of subaerial rocks in puziwan gold deposit and its geological significance
堡子湾金矿区基岩伽玛能谱测量结果及其地质意义 - The tree is an important subaerial object witch should be vividdly described and expressed in 3d gis . people have do some research about the tree model in 3d gis , but have n ' t got a perfect effect
树木是3dgis中对现实环境进行逼真的描述和表达的一个重要地物。在gis领域，人们已经做过一些有关树木模型的研究工作，但效果并不十分理想。 - The yanchang formation is divided , for the first time , into six third - order sequences , each with an average time duration of about 4 . 5 ma . the single sequence is composed of deltaic and lacustrine sandstones , siltstones and mudstones . the subaerial and subaqueous distributary channel and channel - mouth bar sandstone reservoirs are well developed mainly in the lowstand and highland systems tracts
论文在富县探区首次应用陆相层序地层学的观点和方法，把延长组划分为6个三级层序，平均时限4 . 5ma ，各层序由三角洲与湖泊相砂、泥岩沉积组成，主要在低位体系域和高位体系域发育水下(上)分流河道和河口砂坝砂岩储层 - The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes , which , in turn , have exerted a direct and important effect on the sequence stratigraphic development . collectively , the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones . the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage , and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage
系统的储层特征研究表明，该区延长组储层成因类型主要为三角洲前缘水下分流河道、河口砂坝及三角洲平原水上分流河道微相细粒长石砂岩、粉砂岩；储层岩石经历了压实，胶结，溶蚀等成岩作用，历经早成岩机械压实和化学压溶孔隙缩小期、晚成岩a亚期溶蚀作用孔隙扩大期及晚成岩a亚期( b亚期)胶结充填孔隙缩小期三个成岩-孔隙演化阶段；储层物性总体上具有较低孔渗、低孔渗的特点，孔隙类型主要为粒间溶孔、残余粒间孔隙、粒内溶孔、晶间孔及晶间溶孔，裂缝不发育，储集岩排驱压力和中值压力较高，孔隙结构类型以细小孔-微孔隙，微细喉-微喉型为主。
