【摘要】：測(cè)試了采集自黑龍江省塔河地區(qū)的300塊并進(jìn)行拋光處理后的巖石樣本350~2 500nm間光譜反射率、磁化率、密度、孔隙率和金屬元素含量(Fe,Mn,Ti,Zr,V,Zn,Pb,Nb,Co,Bi),并計(jì)算了其光譜吸收深度。在此基礎(chǔ)上,以相關(guān)性分析方法為依據(jù),探討了所采集巖石樣本的金屬元素含量、物性參數(shù)、反射光譜間的特征響應(yīng)關(guān)系,計(jì)算了巖石樣本金屬元素和光譜吸收深度間的相關(guān)性系數(shù)、物性參數(shù)與光譜反射率的相關(guān)性系數(shù),獲得成果如下:(1)在410nm附近,閃長(zhǎng)玢巖各金屬元素與吸收深度間的相關(guān)系數(shù)都存在尖銳的波峰和波谷,相關(guān)系數(shù)達(dá)到極值。(2)巖石樣本金屬元素和吸收深度的相關(guān)性研究中,侵入巖的相關(guān)系數(shù)則顯著高于其他巖石類型。(3)1 400nm附近,巖石樣本金屬元素與吸收深度、各物性參數(shù)與光譜反射率的相關(guān)性都存在尖銳的波峰和波谷。其中磁化率、密度、視孔隙率與光譜反射率的相關(guān)系數(shù)在可見光范圍內(nèi)波動(dòng)變化較大。(4)在1 900~2 500nm范圍內(nèi),金屬元素與光譜吸收深度、各物性參數(shù)與光譜反射率間的相關(guān)系數(shù)波動(dòng)較大,其中金屬元素和光譜吸收深度呈顯著相關(guān),相關(guān)系數(shù)達(dá)到極值。進(jìn)一步研究了巖石金屬元素和物理特性與其光譜特征的關(guān)系,對(duì)于不同巖性的不同波段的反射率與不同金屬元素間分布狀態(tài)的探測(cè),具有一定意義。
[Abstract]:Collected from Heilongjiang area of Tahe Province, the 300 block and 350~2 500nm rock samples are polished after the spectral reflectance, the magnetic susceptibility test, density, porosity and content of metal elements (Fe, Mn, Ti, Zr, V, Zn, Pb, Nb, Co, Bi), and calculated the absorption depth. On this basis, the correlation analysis method based on the content of metal elements to collect rock samples, material parameters and reflectance spectra of the response relationship, the correlation coefficient between the absorption depth of rock samples of metal elements and spectral correlation coefficient to calculate the physical parameters and spectral reflectance, obtained results are as follows: (1) in the vicinity of 410nm, diorite metal elements and the correlation coefficient between the absorption depth are sharp peaks and troughs, the correlation coefficient reaches the maximum. (2) rock samples and metal elements absorption depth correlation study, intrusive rocks related The coefficient is significantly higher than that of other rock types. (3) 1 400nm near the rock samples of metal elements and absorption depth, correlation parameters and spectral reflectance are sharp peaks and troughs. The magnetic susceptibility, density, apparent porosity and correlation coefficient of spectral reflectance changes in the visible range is larger. (4) 1 900~2 in the range of 500nm, metal elements and spectral absorption depth, correlation coefficient parameters and spectral reflectance between the fluctuations, the metal element and the absorption depth was significantly correlated, the correlation coefficient reached maximum. Further studies the relationship between metal elements and rock physical properties and their spectral characteristics, for the detection of the distribution of different lithology of different band reflectance and different metal between elements, has a certain significance.
