1.通过微团聚体分析和微团聚体的显微镜形态观察表明,微团聚体主要分布在0.01毫米以下部分,呈疏松多孔绵絮状态,肥土比瘦土的数量多,且细小孔隙多,颜色也较深暗。0.25—0.01毫米部分,肥土比瘦土的数量少,基本上都呈单粒状态存在,多半是细分散的石英、长石等,颜色较浅,仅含有少量的微团聚体。1—0.25毫米部分,肥土比瘦土的数量多,一部分是团块,一部分是粗砂,肥土的团块边缘呈波浪状,瘦土则较平滑。2.土壤越肥,腐殖质合量越多,腐殖质渗透到土壤细小部分中的也更多,因而形成的微团聚体品质较好。过氧化氢和水对<5微米微团聚体的破坏情况亦证实了肥土微团聚体的稳固程度比瘦土高。3.土壤及<5微米微团聚体分析结果都反映出:土壤肥瘦不同,结合的腐殖质的形态也不同。土壤越肥,紧结态腐殖质合量越高,而游离松结态胡敏酸含量越低。肥瘦间这种差异在微团聚体中表现更为显著,特别是紧结态腐鱼质尤为明显。肥土微团聚体中占总量的72.76%,而瘦土仅为63.33%(土壤肥瘦间分别为58.27%和54.64%)。然而吸着联结态胡敏酸却有相反的趋势,即在土壤中,肥土含量比瘦土高;而在<5微米微团聚休中则反之。我们认为这可能是由于土壤中存在着部分...

Investigations on the mineralogical properties of the important soils developed on sediments in Northern Honan made by X-ray diffraction, polarizing microscopic examination and chemical analysis showed that the mineralogical composition of the soil was closely related to the origin of the sediment materials, but not related to the soil types and the mechanical composition. The main constituent of the clay fraction (<1 micron) of the soils was hydrated micas, at the same time kaolinite, montmorillonite and a few vermiculite were also present. The content of montmorillonite was highest in the soils developed on the sediments of Yellow river, and it was lower in the soils developed on the primary and secondary loess and on the sediments of Zhang river, whereas the least content of montmorillonite was found in the soils developed on the sediments of Xin river.

对豫北平原几种主要沉积物发育的土壤进行了X射线分析、化学分析和偏光显微镜鉴定。结果表明在0.001毫米和0.01—0.1毫米粒级中,这几种土壤的矿物成份与沉积来源有关,而与土壤类型及土壤机械组成关系不大,这些沉积物发育的土壤的粘粒部份(小于0.001毫米)主要成份是水化云母,并有高岭石、蒙脱石和少量的蛭石。黄河沉积物所发育的土壤含蒙脱较多;漳河沉积物、黄土、次生黄土所发育的土壤次之;沁河沉积物所发育的土壤含蒙脱最少。在0.01—0.1毫米这一粒级中,原生矿物的轻矿物主要由石英、长石和云母组成。重矿物在黄河沉积物中以普通角闪石为主,沁河和漳河沉积物以磁铁矿为主。最后讨论了根据矿物组成来推测沉积物的来源的可能性。

While linear relationship exists between porosity and depth of burial of sandstones at the northern flank of Bei Dagang structural zone, the opposite is true in the case of the sandstones at the southern flank, where at the depth of less than 3,500 meters, the porosity of sandstones decreases with their increasing depth till 3,500 meters when the curve assumes an upward trend, and at 4,000 meters there occur sandstones with an average porosity of 14% to the maximum porosity of 20%. This is attributable to the...

While linear relationship exists between porosity and depth of burial of sandstones at the northern flank of Bei Dagang structural zone, the opposite is true in the case of the sandstones at the southern flank, where at the depth of less than 3,500 meters, the porosity of sandstones decreases with their increasing depth till 3,500 meters when the curve assumes an upward trend, and at 4,000 meters there occur sandstones with an average porosity of 14% to the maximum porosity of 20%. This is attributable to the preservation of a part of the primary porosity in the rocks due to the formation of high porosity pressure. The increase of porosity pressure may effectively check the action of compressive solution at the granular contacts and reduce the extent of secondary enlargement of quartzites and feldspars. It is presumed that the high porosity pressure is resulted from differential compaction of sandstones and mudstones in the process of their diagenesis.

北大港构造带北翼砂岩孔隙度与深度的关系为直线型,而南翼砂岩孔隙度与深度的关系为曲线型。南翼在3500米以上,砂岩孔隙度随深度增加而减少,到3500米有回升趋势,而在4000米的深处还有平均孔隙度为14%,最大孔隙度20%的砂岩。这种现象产生的原因是保持了一部分原有孔隙度,而保持孔隙度的控制因素是形成高孔隙压力。由于孔隙压力的增高可以有效地减低颗粒接触处的压溶作用和石英、长石次生加大的范围,而这种高压往往由于砂泥岩差异压实作用的结果。
