摘要:... An earlier attempt of dating based on feldspar IRSL chronology shows a combined effect of anomalous fading and unbleached components resulting in age inversions. The present work tries to explore the possibility of using blue light stimulated luminescence (BLSL) of quartz, in...

摘要:... We, for the first time, developed a promising method to mineralize CO 2 using earth-abundant potassium feldspar in order to effectively reduce CO 2 emissions. Our experiments demonstrate that, after adding calcium chloride hexahydrate as an additive, the K-feldspar can be tr...

摘要:Abstract(#br)In the granite-NaF-H 2 O system, there exists a nucleation lag in the course of alkali feldspar crystallization indicated by experiments on crystallization kinetics. The nucleation lag time is about 18 h at 700°C and about 6 h at 650°C. Meanwhile, both nucleat...

摘要:... As an alternative to overcome this difficulty, we explore in this work the possibility of relying on feldspar minerals rather that on quartz to perform in situ -produced 10 Be measurements in such environments. Our strategy was to cross-calibrate the total production rate o...

摘要:... This study presents a novel method to reconstruct soil reworking rates on such timescales by utilising luminescence signals from individual sand-sized feldspar grains as soil reworking tracers. We propose a post-IR IRSL procedure to harvest two luminescence signals from indiv...

摘要:... However, feldspar is required where quartz luminescence properties are inappropriate for dating, as is often the case in geologically young mountain ranges and areas with young volcanism. Here we aim to evaluate the potential of single grain feldspar luminescence dating appl...

摘要:Abstract(#br)Feldspar belongs to aluminosilicate minerals with a huge reserve, accounting for at least 98% in soil minerals. Oxalic acid is the common organic matter in the natural world, having three configurations (H 2 C 2 O 4 , HC 2 O 4 − and C 2 O 4 2− ) dependent on...

摘要:Abstract(#br)Presence of iron compounds as impurities in kaolin and feldspar, impart reddish colour to ceramic products manufactured using these minerals. The quality of kaolin and feldspar was enriched mainly through iron removal by biological methods. Bacteria isolated from kao...

摘要:Abstract(#br)The thermoluminescence (TL) properties of raw and annealed feldspar have been studied for their use in gamma dosimetry. The raw gamma exposed feldspar shows glow peaks at 120°C and 319°C. Gamma dose beyond 500 cGy can be measured without any significant fading...

摘要:... The general agreement between ages based on the quartz OSL, feldspar IRSL as well as feldspar IR 50 and fine grains IR 50 was obtained for well bleached samples, while feldspar pIRIR 180 overestimated it. Based on age–preheat plot, where feldspar pIRIR signals using vary...
