摘要

矿岩在Kraków-Częstochowa高地很常见,但地球科学家很少探索它们。除了许多充满生物沉积物的形态洼地外,沼泽也发生在河谷内,通常位于峡谷的上游。Białka河谷(Krztynia的左侧支流,上Pilica流域)内沼泽形成的加剧可能受到基岩中渗透性差的河流粉质砂的影响。Młyny凹陷的充填是通过以碳酸盐沉积中断的局部沉积为特征的河流沉积和原生有机质的沉积完成的。前者沉积物类型以矿物-有机沉积粉砂为主,以细粒组分为主,主要赋存于岩心的基底,砂粒组分主要赋存于岩心的上部,上覆于钙质-粘土砂层。灰分含量高达87%,铁浓度周期性升高(30 ~ 48 mg/g)。研究的牛轭泥沉积中也存在碳酸钙(CaCO3),在某些层段中碳酸钙含量超过40%,说明地下水在Białka流域水平衡中起着更重要的作用。这一时期由于较高的洪水活动而周期性中断,并由矿物沉积物记录下来,这些矿物沉积物具有特定的颗粒组成特征,并且作为节奏物沉积的有机物的百分比升高。通过放射性碳定年在1885±105 BP的地层中发现的微量元素浓度升高可能表明,由于经济适应当地条件,人类对环境产生了影响。人类活动的地球化学记录由Białka河谷集水区各部分的考古数据证实。研究核心区顶部区间微量元素浓度最高的原因是Silesia-Kraków地区经济发展强烈,以及与之相关的毁林、采矿和冶金活动。

Lithology and chemical composition of a Neoholocene palaeochannel infill within the Białka River valley, Kraków-Częstochowa Upland
Mires are common in the landscape of the Kraków-Częstochowa Upland, but they are rarely explored by Earth scientists. In addition to numerous morphological depressions filled with biogenic sediments, mires also occur within river valley, usually upstream from gaps. The intensification of marsh formation within the Białka River valley (left-side tributary of Krztynia, upper Pilica catchment) may have been influenced by the occurrence of poorly permeable, fluvial silty sands in the bedrock. Infilling of the studied depression at Młyny was accomplished via fluvial sedimentation characterised by local aggradation interrupted by carbonate precipitation, and sedentation of autochthonous organic matter. The former sediment type is represented mostly by mineral-organic aggraded silt with a dominant fine fraction, occurring mostly in the basal part of the studied core, and sand fraction in the top interval of the core, superjacent to calcareous-clay gyttja. Ash content reaches up to 87% and Fe concentrations are periodically elevated (30–48 mg/g). Calcium carbonate (CaCO3) also occurs in the studied oxbow mire deposit, exceeding 40% in some intervals, which indicates that a more important part was played by groundwaters in the water balance of the Białka valley. This periods were periodically interrupted due to higher flooding activity and recorded by mineral sediments characterised by specific granulometric composition, and an elevated percentage of organic matter deposited as rhythmists. Elevated concentrations of trace elements noted in a horizon dated at 1885±105 BP by means of radiocarbon dating may point to human impact on the environment due to the adaptation of economy to local conditions. The geochemical record of human activity is corroborated by archaeological data from various parts of the Białka valley catchment. The reason for the concentration of trace elements being highest in the top interval of the studied core is the intense economic development of Silesia-Kraków region, and the associated deforestation, mining and metallurgy.
