LumenStone Dataset

Description

The material used was collected from 30 ore deposits of the CIS. Prepared samples of polished sections were analyzed using a Carl Zeiss AxioScope 40 microscope, photographing was carried out using a Canon Powershot G10. Samples represent the main ore associations and are categorized by deposit genesis.

LumenStone dataset was created to unite high-quality geological images of different mineral associations which can be used for different tasks of geological image analysis:

  • S1: association of hydrothermal ore of Berezovskoe deposit consisting of sphalerite, pyrite, galena, bornite, tennantite-tetrahedrite group, chalcopyrite minerals. Aimed for segmentation task, pixel-level masks provided.
  • S2: association of Layered Ultramafic Deposits (Deposits of the Norilsk Group), consisting of pyrrhotite, chalcopyrite, pentlandite, magnetite minerals. Aimed for segmentation task, pixel-level masks provided.
  • S3: common association of high-temperature hydrothermal ores consisting of pyrite, arsenopyrite, covelline, bornite, chalcopyrite, magnetite (ordinary and copper-bearing magnetite), hematite (secondary and hydrothermal) minerals (coming soon). Aimed for segmentation task, pixel-level masks provided.
  • V1: A specialized dataset featuring the same samples as for S1 imaged under varying conditions, aimed at developing and testing color adaptation methods.
  • P1: A collection of images of polished sections, designed for constructing panoramic microscopic images. Each sample is represented with 20-25 partially overlapping images.

All methods of image processing and analysis for microscopic geological images of polished sections, which were developed by our team, are collected in python package petroscope and are available for free use.

Versioning system

LumenStone dataset is actively updated and expanded so for convenient usage each set supports versioning system. Every new version of set besides offering new images will contain all images from the previous version. Image annotations can be modified and expanded from version to version. All outdated versions as well as the latest ones are available for download.
