从全党全民大搞鋼铁以来,铁的风化矿床成了鋼铁工业遍地开花所用矿石的主要来源。这是由于它分布广的特点所决定的。高要专区在五八年的铁矿普查中,經統計,风化褐铁矿块体堆积矿床达50-95％。通过工作中的摸索,对于它的特点和普查勘探方法有如下体会。这种类型鉄矿的特点是:矿石矿物主要为褐鉄矿和少量的赤铁矿;矿石呈褐、褐紅、棕褐、黑褐等色;矿石結构致密或多孔,呈块状体夹于基岩上面的第四紀松散堆积物中,块度大小不一,时而见1～2M的直径,时而见1～2Cm的直径,分布不均勻至极不均匀;含矿层为似层状,矿量从数万至数十万吨,含鉄30～50％,一般是含铁的砂岩、砂質頁岩、砂
Since all the people in the party engaged in the steel industry, weathered iron deposits in the iron and steel industry have become the major source of ore used in the iron and steel industry. This is due to its wide distribution characteristics. Gaoyao area in the iron ore census in 1988, the statistics, weathered lignite ore deposits of 50-95% block. Through the exploration of the work, I have the following experience about its characteristics and census exploration methods. The characteristics of this type of 鉄 ore are: ores are mainly brown iron ore and a small amount of hematite; Ore is brown, maroon, tan, dark brown and other colors; ore structure is compact or porous, Quaternary loose bedrock above the bedrock, the block size varies from time to time to see the diameter of 1 ~ 2M, sometimes see 1 ~ 2Cm diameter, uneven distribution is extremely uneven; From tens of thousands to hundreds of thousands of tons, containing 鉄 30 ~ 50%, usually iron sandstone, sandy shale, sand
